Things are marching on with the MuSeq sequencer for the MU style modular synth. The pre-production PCB is assembled (couple of extra mod wires).
MuSeq has a number of modes and features, so I’ll explain them here;
- 2 Channels of sequencing, A & B (channel A shown above)
- Channel A has the following modes;
- Note (1V oct but scaled to 12 notes)
- Step Length (variable from 1/32 to 1/1 with triplets)
- Gate triggers (1, 2 or 3) commonly called “ratchetting”
- Gate On/Off
- Channel B is linked to Channel A, but still has the following modes
- Note or CV (512 value resolution)
- Gate Triggers (1,2 or 3) same as channel A
- Gate On/Off
- Legato Mode
- you can change the first step,
- the last step
- direction (forward, backward, pendulum, Fwd/bck and Random currently)
- Syncable from MIDI or internal clock currently, will be adding Sync24, USB MIDI sync and also a pulse input from other modules in your system
- Digital output (x2), one for Run/Stop and one for clock out (from 1 beat per bar down to 32 beats per bar)
- Inputs (x2), can be used for Tempo, Channel A note, run stop, clock input, pattern change.
- Bank play mode, this lets you chain up to 8 patterns together, with the added advantage that you can enable/disable patterns on the fly and set a number of repeats for each pattern. So you could have pattern 1 play 3 times, skip patterns 2 & 3 and then play pattern 4 once, then skip patterns 5,6,7 & 8 and go back to pattern 1.
- Loading and saving of 8 banks of 8 patterns to an SD Card in text format, making it easy to share patterns.
- USB updatable
There’s a way to go with the software but most of the features listed above are already in. I’m confident by the time the first production run arrives I’ll have got everything in.
One of the main goals for this was to make things smaller, I love sequencers, but loosing 8U of rack space to get 2 or 3 channels of fairly limited sequencing didn’t really appeal.
MuSeq is 3U wide and has two channels and of course you can get up to 64 steps per channel with variable gate lengths without sacrificing a channel to do that!
I’ve endeavoured to keep the “analogue sequencer” feel as much as possible, but sometimes I think adding some digital into the mix makes for a truly powerful sequencer.
Below are a few images from the prototype showing the various “pages” which are selected by the knob just below the tempo knob.
More updates as they happen!
