RIT_M RhythmSequencer

SDS Digital

This 4HP'er let's you tap in a rhythm, creates a clock and T/G plus an on-the-fly programmable CV Sequence

As this is a brand new sequencer prototype that can be a Rhythm Sequencer, Tap-Tempo, CV recorder, Gate recorder, and pressure pad sender all in one.
There are several intuitive / automatic Modes in this module that are based on how a sequence is started, and what is patched into the I/O jacks with only a primary settings menu (set & forget) to suit your setup.

The RITM has two variable touchpads, one to tap in a rhythm, and the other to define the loop point. A clock is derived based on this rhythm, loop size, and settable BPM range(i.e. 60 to 120BPM or 90-180BPM). The resulting clock is panel adjustable from 1 PPQN to 96 PPQN.
The "Magic" Clock jack is bi-directional so the RIT
M can be the source clock, or be clocked by an external source so your sequences align with existing clocks.

Beat Quantized... or Not:
Beat quantizing can be turned off to allow complex swing style rhythms that still follow the clock in/out but don't snap to "steps" as with most sequencers. If beat quantizing is turned on, the clock divisions (PPQN) can give many micro divisions to a clock so rhythms can snap to beats. The choice is up to you!

Gate Output:
The trigger/Gate output is precisely the beat you entered by tapping the RHYTHM pad. The duration of each tap will also be output so long "notes" can be achieved during recording a sequence by just holding the pad.

CV Output:
The CV output's default function is to output the CV knob position at the time of recording. This allows real-time control of a VCO, filter element, VCA etc.
Moving the CV knob during a sequence playing will momentarily "take over" the CV output jack, and any tap on the Rhythm pad will update the nearest "beat" with the new CV for a loop time after knob is moved, after which the Rhythm pad returns to adding/deleting beats to/from the loop. This is especially useful if controlling a VCO.
There is also a CV quantizing option.

CV input Record:
The CV input gives a CV record capability. New CV's can be laid on to a playing rhythm based on CV change keeping the rhythm but with new CV levels and is continuously updating on any CV change. Can also be used along with the Reset I/O jack which acts as a gate input during a fresh recording. The Gate output will output this signal during record for instant auditioning.

CV input Play:
While playing a sequence, the CV input becomes an offset for the playing sequence at 1V/Octave but non-quantized so the sequence CV can be modulated without using a summing module. Simply unplug the CV in, then plug it back in.

Smooth CV Record:
Smooth recording of a CV pattern can be realized if there is no rhythm. The CV pattern will proportionately speed up or slow down with varying clock rates input or selected. As a clock master, the recorded CV pattern can follow the clock divisions as selected. Reset input will re-start the pattern.
Clock output is derived as usual (if no clock input) and beats (gates) can be added to the smooth CV sequence while playback looping. Smooth CV can be up to 2 minutes long.

Gate Recording:
An external gate/trigger can also be recorded. This means a CV keyboard or sequencer can be recorded. When recording this way, the CV input becomes smooth CV so can record portamento or glissando from a keyboard. Simply tap the Loop pad to arm and play away!

There is now a velocity output that is based on the strength of the rhythm tapped in. The finger pressure on a multiple element sensor and proximity ramp is taken into consideration to calculate the velocity of any tap.
Pressure is also recorded which is great for controlling say a filter on long notes.(prelim.)

Reset Input:
A sequence can be restarted for alignment using the reset jack. The reset jack will output a pulse on each loop cycle until a pulse to reset the sequence is received, so it's bidirectional.

Saving Sequences:
3 sequences can be saved to permanent memory for recall after next power-up.

Slaving / Multiple RITM Modules:
Each RIT
M has a Link I/O behind the panel so several RITM's can be connected together and work in tandem for multiple CV/Gate control. The Rhythm pads can then be played and will remain inside the same sequence, or can be separate but still using the same clock. As the RITM can output a clock or step from a clock input at different divisions, post patching from one to another makes the possibilities endless!

- Rhythm Loop size is nearly unlimited. (Smooth CV up to 2 minutes)
- CV's in sequence can be changed on cue / tap
- Beats can be added/ removed with a tap or hold on Rhythm pad
- Tapping Loop pad will reset a sequence / restart a stopped sequence (on clock point)
-Tapping Loop pad from a full stop will arm to start recording a sequence on a pulse on Reset input
- Doubles as a straight tap tempo, great for delays that are clocked
- Doubles as a CV quantizer (1V/Oct) with offset while not looping / recording
- Records the CV knob/CV input smoothly without a rhythm playing and can be re-triggered
- Can output Velocity CV based on pad pressure alone or during a sequence
- Touching both pads momentarily will arm playing sequence to pause at next loop point
- LED's indicate PPQN selection while changing
- PPQN (>last) only updates at loop point so never falls out of sync.
- Fancy pad LED's indicate running condition by color
- NEW: Sequential Master-Slave Linking to sync multiple units, clocks, loop points, from master.

The whole idea of this module is to quickly add sequenced T/G/CV control of other modular elements, on-the-fly, without setup time or large HP, displays etc. I think it's a very useful tool and look forward to moving it from the grid board into the rack for demos!

Price breaks:
Because of the great possibilities of cascading the RIT_M, purchasing multiple modules drops the price.
