This is a 58hp, 6u case. The purpose of the rack is to provide utility and processing FX for my PWM Malevolent, which has two oscillators, a mixer, a filter, two ADSR envelopes, and two VCAs.

I also have a 0-CTRL, an Erica Matrix Mixer, and a St. Modular Workbench.

Any feedback welcome.

Everything is always sold out?

Today I installed the first modules and made my first patch. Envelope triggering the springreverb. Springreverb into the filter. Lowpass into the mixer. Highpass into the black hole and black hole into the mixer. Sounds realy haunting just what I was looking for. Stroking the spring with my fingers, feedback, I am verry happy! while i was patching away I realized that another mixer with a gain/overdrive (as a sub) would be verry handy.

nice i just got a Tripple sloth,havent put it in my case yet

Does anyone know if the Current Draw on the CalSynth Rand is the same as the original Marbles? The data is currently blank on the Module's page.

thanks

Very interesting! using four identical modules as a Mixer
-- RaymondHu

Thanks. 2x stereo strips are used for my voices (2x legion thru Steiner VCF as a complex osc for bass, CI thru SSG for melody) and then the other two are used for external gear like drum machines etc because they have pre amps for inputting line level gear. The NE stereo mixers are for delay and reverb sends (stack cables from the stereo strips go into them). Everything is then summed by the ES-9 so you can jam live while recording all the tracks separately. You can also have per-channel side-chain by using time warp as an envelope follower, inverting and offsetting the output with OSD and then inputting that signal into the stereo strip vcas on every channel that you want the side chain to apply. This all took a lot of figuring out but it works incredibly well

Hi there,
Ashiko was designed to smoothly modulate an audio signal in the stereo field using only a single CV source.
I suggest you to check out this new demo video by BRiES that goes really deep into Ashiko functionalities:

Vaemi's new module XFMR VCA, which is designed for Eurorack systems, introduces users to a transformer-based VCA design.
Turkey-based Vaemi (Volt Age Electronic Musical Instruments), which commercially produces synthesizers and electronic musical instruments, recently released its first module, the Osi-Op (through zero fm VCO), and quickly followed with other Eurorack modules such as Shift Register, R2R Ladder, Buffered Multiple, making a name for itself. Now, it has introduced and brought its users the new XFMR VCA module, which is handcrafted with high-quality, through-hole components and features an audio transformer in its output.
The XFMR VCA is a VCA with linear curves. It has two separate audio outputs, such as the classic Op-Amp and the Transformer Output feature that gives it its name. It is AC Coupled and designed specifically for audio signals, making it a VCA module that you would want to use at the end of your chain. You can use it to add saturation, harmonics, and EQ to your patches made with the Osi-Op and through zero fm techniques, or use it for a clean range if desired. This wide range of options will be loved and make you feel comfortable.
Additionally, the XFMR VCA has an expander that allows you to expand it up to 3 channels. With the expander, you can have two more exponential VCA channels, which you can use for frequency modulation of oscillators or in other places you need them.
In studios, preamplifiers are equipment that can properly raise the microphone or line signals level without distorting or adding noise to the sound. However, when recording analog synthesizers, we tend to lower the sound instead of raising it because they have very high outputs. At this point, we thought that one of the most important things that preamplifiers add to recordings, other than gain, is audio transformers.
The XFMR VCA also has an EQ stage. This will provide great flexibility when finalizing your last patch, especially in multi-channel patches, and will provide a more accurate and clean sound in live performances.
Vaemi aims to create systems that can comfortably be used in today's electronic music and popular synthesis techniques such as additive, FM, Formant, Subtractive synthesis, and will continue to shape and evolve with new module designs that will be released in the coming year.

My new video is online! It is a jam with some new modules by Mutable Instruments. It starts out as an ambient piece and then in takes you to unexpected places!

There is also a question that I ask especially for the lovers of modular synth video so could you let me know what you think? I would love your feedback and grow as a content creator of modular synth video's. Thank you so much!

A clock divider from Frequency Central with 4 sub-clocks, which is pretty useful.
Straightforward build, nothing challenging, good mid-level experience ,
And the unit has tons of functionality, I only touch on some during the demo (if I had a 4 input scope I’da covered more, gives me an excuse to buy one). Look at the manual on their web site for all the details, there is a lot going on with this.
Good utility module.

Hi guys

As before, also a newbie, but my problem is that I do not know anything at all. At the moment I try to watch different lessons on YouTube and try to repeat them. I am wondering if there is an online resource where you can try for free how to sound and use different models, or am I just blind?

Understood.

But Yeah, I'm not sure that helps or maybe it means I'm actually calibrated alright.
Testing the Beatstep Pro on a regular Oscillator gives me the whole keyboard range without problems.

I wish I could filter/sort by whether a module is in the rack I am currently viewing...
...Not sure how generally useful this feature would be...
-- adamj

+1 from me!

Not really a function but i noticed that it is not possible to filter for polyphonic modules...
may be it makes sense to include polyphony in the function list!?

... the notes are all the same from G upwards...
-- wishbonebrewery

Dont't know if this is helpful...
I tested mine by routing the pitch input through the mordax data voltage monitor.
My Rings takes voltages from 0.0V to 5.54V. Everything higher than 5.54V is ignored.

I've just tried a re-calibrate with the Frequency knob set to 12 o'clock and its made no difference, the notes are all the same from G upwards though going down the octaves is totally fine.

The Jolin Ashiko seems to be an interesting module. Can anyone tell, if it allows for smooth panning between left and right? Is it possible to smoothly move a sound through the stereo field from one side to the other? Or if it's more like switching: signal is either hard left or hard right? That's not 100% clear from the demo videos available, at least to me. Thanks for helping.

Yes, I didn't consider module depth for a specific case. It looks like a 4MS Pod20 can support modules up to 34mm deep.

I figured that anything in the rack you posted was fair game for this hypothetical 20HP system.

20HP is a very significant restraint... are you planning on using this small case with others at some point? I personally understand and appreciate the attractiveness of small cases for focusing on and learning specific modules, but 20HP feels much too small as a standalone unit. Do you already own a case or any of these modules? Or are you in the beginning stages of planning out a system? If you are just getting into eurorack, I would recommend getting a larger single case, rather than several miniature ones. This is advice that you will hear quite frequently on these forums.

first 20hp standalone and later with other hp ascending pods, because the restraint random chaotic is ok, i was thinking delta-v, bongo cv and athru

Really nice design, would look even better with the "Eras" font used on the original Serge modules.

I know - looks rad!

Thank you for the interesting challenge. This was the most functional and interesting combination that I could come up with in the 20HP limit.

I soldered all the bits on a kit from Pusherman https://pushermanproductions.com/product/full-kit-mutated-rings-w-black-aluminium-antumbra-panel-smd-pre-soldered-pcb/ last weekend, followed the calibration procedure and all looked to calibrate ok.
But I notice when playing notes on the Beatstep Pro that the upper keyboard ranges seem to all be the same note passed a certain point which makes me wonder if the Pot positions should be centered or something versus all set at zero prior to calibration.

Any thoughts??

Thanks

I would like to see a function category added for modules like the Neuzeit Instruments Quasar and the Joranalogue Audio Design Enhance 2. Perhaps called Stereo Imaging? The closest category right now is Dual/Stereo which brings up dual ADSR's and other unrelated stuff.

How well does Octatrack handle modular level signal? You may find that you need a few modules to step down to line level or instrument level. I don't have an Octatrack so I have no idea if the modular signal is too hot or clips.

Going for mainly an effects rack that I can feed into an octatrack

4 outputs of yarns go into a a bunch of external gear that will be fed into the zlob/erica mixers.

Basically Ch1-4 of the clump will be fed by the erica and zlob mixers. Outputs of the matrix mixer will go to a sherman filter bank, beads, electus, the zlob fixed filter bank.

Those ouputs will go into an octatrack and then into the vortices along two machinedrum tracks (6 total)

I guess I'm losing a lot of cool stereo stuff so if there is a smarter way to route this with other modules or anything I'd love some suggestions

any help would be super appreciated!

Can you imagine a film with just a few stars and no supporting cast, no extras, not even a little furniture in the set? This is the unconscious bet and the mistake we all make a little too systematically when we approach the modular synthesizer and in front of all its big stars (Clouds, Rings, Morphagene, Basimilus, Bloom, etc.)

Nothing really important to add to what others have said here.
Modular is a bit like cinema. ModularGrid is not the USC School of Cinematic Arts, or the Ecole Nationale Louis-Lumière. But you've come to the right place. The amateurs and even the less amateurs have almost all passed through the benches of ModularGrid :))

Progspiration is offering excellent guidance. You will need more space to get the most out of this. You can read back through years of beginner posts here, and so many of those new to modular have a similar tiny case idea, and the guidance is and will always be the same. Yes, a tiny case will make sound, but it won't be interesting for very long. Get a bigger rack to start with. You will want and need to expand quickly if you don't want to get frustrated with the limitations of this proposed palette case. The goal is for this instrument to provide years of fun and inspiration, so give yourself room to grow into a versatile rack that won't be stale in a few months.
Maybe it only makes sense after you get your hands on a few modules. My own initial plan was actually to have a decent sized 9u 104hp beginner rack, and that quickly doubled within a year's time. Once you understand the value and necessity of attenuverters, envelopes, LFOs, VCAs, switches, S&H, logic, and all of the other stuff that makes a synthesizer work, I think the general beginner guidance starts to make more sense.
Have fun and good luck!

I agree with Progspiration on almost everything he said - basically you are trying to do too much in too small a space

either start with a bigger case or massively scale back what you are trying to do

you'll need more modulation - and someway of mixing the 'ordered' modulation with the chaos - a matrix mixer in my opinion is best for this - and one that is usable - ie ergonomic and therefore quite large - I like the doepfer - plus more attenutaors - not just vcas (and you haven't really got the envelopes to open and close the vcas anyway

I'm not really convinced that the combination of the poly chromatic and bloom will work very well together - I think you really need at least one (preferably 2) channel(s) of proper sequencing (or a midi sequencer) to make the most of poly chromatic - one channel to determine the root and another to determine the chord type

personally I would go for the bigger case and spend a decent amount of time (a week at the very minimum) thinking deeply about the hints in my signature... you will end up with a much more versatile modular for less cash (in the long run)

Link directly to rack for reference : )

It's extremely common for newcomers (myself a year ago) to want to start small and think it'll hold you off before you expand, but cases are a real expense. If you know you're going to expand, you might as well start with a case that will allow you to grow into it. I started with a Tip Top Happy Ending kit (3u, 84hp), got a second set of rails and mounted them in a box (6u, 84hp), but by month 4 or so I had already filled that and knew there was more functionality I needed. I recently got a 9u 104hp case from Case From Lake that closes patched and would recommend them in a heartbeat. It's just one guy out of Italy so took a little while for it to get finished, but well worth the wait. Otherwise, the Tip Top Mantis is the best bang for buck case, has a great power supply, and really is quite portable. Those Palette cases look cool, but are substantially more $/hp for what they are.

Looking at your assortment of modules, I think you will run into some additional needs quite quickly in terms of utilities, which in the Palette case you won't have room for. EG Monsoon reeeaaaalllly needs attenuation on modulation, and right now you only have the 2 vcas in the 1u row that can scale back in that way. Sloths is going to swing those parameters pretty wildly, particularly if you use those bottom +/- outputs which can go outside the +/-10v range. Sloths is also chaotic by nature, and I think you'll find that having something that can do "normal" LFOs is extremely useful.

Those are the things I've noticed for now. The modular journey is incredibly satisfying, but once it gets its claws in you you're going to move up in hp quite quickly : )
