Hey Tobi,
First of course, thanks for the detailed reply, I've definitely taken a few things on board!
Second... I think I've found the golden combo! (have adjusted the grid if you see)
So I dumped the oscilloscope, because for now the system is connected to Ableton, and I have a decent oscilloscope there. Also dumped the pressure pads, and added the buff mults to the 1U rack (only $39 each?!). I already have one 1U buff mult so this makes sense.
I replaced the 2hp mults with 2x 2hp ADSRs which along with maths and Zadar should cover my envelope needs I think.
And finally.... 2x Doepfer A-121-3 !! Analogue, dual-mono or stereo filters with grit, aaandd great cv control too. Check !
Regarding the Bloom, I chose this because I like the idea of writing a "riff" which I can go mad with, and then quickly snap back to. Very useful compositionally. That, along with the Keystep and maybe Ableton, should give full freedom to go totally nuts, and then come back to a motif nicely.
As for MATHS, unfortunately it's very very difficult to sell any module as I'm in India, so I'm stuck with it. Not to say that's a bad thing, it's a super module, but more spending + no returns = :*(
I forgot to mention, I actually have a great interface (Antelope zen tour), which has an insane routing matrix. This means I can route vocals/guitars/other instruments directly into my modular, or take my modular signal and run it through an instrument level fx loop and back in, and monitor all with zero latency. Very cool. Only limited by your imagination!
Heheh yes, the case took me quite some time. Because first I was going to get a 4U skiff from Intellijel. Too small. So I looked at the 7U skiff from them. Not deep enough for the Expert Sleeper modules. So then I did some research, and built this case for $250, power included :P
I like this system too, because it makes expanding very easy, just buy rails, power board, and build with home made materials. Add some latches and rubber feet, (and maybe a stand soon...) and voila!
