Hi, first off congrats on designing such a well thought-out and feature rich module
! I really think it offers something that's not been done before neither in such a small package (like, hold on for a minute; eight sequencer tracks!!) nor probably in any form, software or hardware, if you take into account everything that's under the hood: e.g clock dividers, probability, ratcheting.
So, again, I really want compliment you on such an impressive engineering and user interface achievement, and if you are open to some more suggestions, here are some I want to share. I'll be speaking mainly from a live performer's perspective, and (if that means something) I normally don't do that: most designs/prototypes shared here look quite solid and, again, well thought-out, so there is not much that I can add. However, in your case the concept behind the module and actual execution are so brilliant that I see potential for this to become a key element of a live performance oriented system and as one who deals with this kind of things on stage, here's some input I can provide on what features I'd like to see present in a sequencer for easy and convenient operation in context of playing live.
First thing that I wanted to suggest was a real-time recording of notes, and on quick inspection I found this line specifically mentioning ♦ Quantized Live recording (Cvs and Gates) — which, needless to say, I find just a w e s o m e
! Looking at the panel I assume it works volca/electribe recording style: you press rec, then quickly play a line on sixteen buttons at the bottom like a mini keyboard, and the machine loops the phrase exactly as you played it (only quantized to the clock, and with respect to rests). By looking at the panel with orange keys outlined I think it's exactly how it works, but if the layout is still subject to change, what would you say if I suggested to move a keyboard two buttons to the right, and repurpose leftmost ones to octave up / down function? This way, you could play parts that span more notes, or — alternately, — if encoder can switch octaves, I'm equally fine with this too. Works well for me in volca, pretty smart.
A lot of KORG gear is using this nifty feature called "Active Step", where you remove steps from sequence, and it starts looping around those (8 / 7 / arbitrary number) that you leave. Any chance of seeing it implemented here? From my experience, performance-wise it's an interesting one to play around, and while I see you mentioning different pattern lengths per track, there's more than a single way of going about it: most sequencers handle it just by shortening a sequence by n steps, whereas in KORG case, you can deactivate any arbitrary steps: e.g 3, 4, 7 and likewise. I'd really like to see this possibility here as well.
After playing a lot with KORG SQ-1, one of the most liked things about it for me is easy & quick voltage range adjustments: 1V/2V/5V/8V etc. This is really cool to have, and the way it operates I can in one touch transform my bassline to melody in one track or two, and vice versa. The way it is achieved there is holding the Function button, and then 16 rubber buttons allow to do this via 8 buttons on the left as well as changing sequence scale from chromatic to minor to major to no quantizing. This has inspired the thought of a special performance mode on Eloquencer which would too repurpose those and give them similarly useful functions. Yet, given that notes aren't set with knobs, but stored in memory, I suggest a little different approach: instead of attenuating the voltage, sequence depending on its note range will fall into the nearest suitable slot, and a led button will indicate that. I.e: the top left 4 buttons will shrink or stretch our sequence to narrower or wider range and we will see which of them it falls into by the notes that it contains. It will also be useful visual indicator of how wide is it in its range: e.g if first led is lit, its octave or less, or two in case of second etc.
As to the other buttons, I suggest they affect various other important parameters, but also in a relative way so that you could quick get back to where you were a second ago with a touch. For example, the bottom four buttons could change gate length: if in a sequence you programmed they all are more or less short, it'll automatically fall into the first slot, and buttons to the right will increase the duration in 10-25% increments with respect to the length of each that is already contained in a pattern. If it's long, the button 4 will be lit then and ones on the left will chop/truncate the seq — you get the idea.
The last eight buttons is where it gets interesting, here I came up with something I've not seen anywhere before: this will change the gate length of only odd or even steps from original to say, 25-50-75%. I think this can be a nice way to alter the pattern with respect to its rhythmic content: shorter hits on downbeat etc. But! That is not everything, and as we stil have four more buttons, they will switch between four settings: a) gate length change only affects odd steps; b) gate length change only affects even steps; c) & d) gate length only affects each second step among the active ones (gate on).
This is pretty much it, hope some of this will be considered for a possible addition. Really looking forward to the finished module.
