Note to Delay Time modulation not really working as expected (desktop model)

So on the desktop model I can modulate “note” to “delay time”. I expect it to work like this: delay time is dependent on the register I play a note in. For example a lower note will give me a short delay time while a higher one will change the delay time to a longer time (or the other way round, doesn’t really matter, depends on positive or negative modulation of course). However it seems to work only every other note. Like, if I play a note repeatedly, it will change the delay time eventually, but not the first time. It’s really frustrating. The same goes for velocity to delay time. Is this a bug? Does anyone else experience this?

Have you got Binaural turned off for 12 note poly?

A bunch of the mod assignments are only consistent in Binaural mode due to (I paraphrase badly) there only being 6 mod address pathways which get shared between all the voices. This is true for key tracking as well as some other mod sources. It’s mentioned in the manual in a few places.

If not then I dunno!

Hi,

it happens regardless of 12- or 6-voice mode.

I have a desktop too I will check it out.

I use the note mod source a lot n occasionally I’ll notice something like you mention but I’m usually on such a whirling journey that I’m on to the next thing before I know it. Retrospectively I imagine it may’ve been the 6 vs 12 thing but obvs not in this case, let’s have a gander.

Love the desktop form factor though ey?

Negative note modulation for filter and envelopes should be a standard pre-wired setting imo, so glad they implemented the note mod source on the desktop.

I think it’s limited by the fact that there is just one delay. It will never work polyphonically. How would you decide which note sets the delay time? The last one triggered? I also assume that abrupt changes to delay could result in glitches. Which could be used creatively IMHO.

It doesn’t even work when I play just single notes. And yes, I absolutely am looking for those glitch sounds.

yes the last one, as the Access Virus did approximately a billion years ago.

@cube48 is correct: I’m getting similar results on my desktop in polyphonic mode - the delay time change isn’t instantaneous, but sometimes requires several note events to be triggered before it occurs. (I tried to attach an audio file of the results but audio isn’t accepted for uploads here)

Here’s what I used to check:

MIDI: 16th-note length pulses @ 1/4 note intervals, played successively in groups of 8 on notes c1, c3, c5, c7, ending the sequence with 8 pulses on note c1.

Patch: Init Patch
Tempo: 60bpm
Modulation: Note → Delay Time
Mod. Amount: +100%
Delay Feedback: Minimum (results in a single echo)
Delay Level: around 80% (3 o’clock)
Mode: Binaural

Expected behavior:
8 pulses @ a given pitch with a delay time of x, followed immediately by 8 pulses @ a higher pitch with a delay time of y ( with x < y ), and so on, until the penultimate sequence where the final drop in pitch should result in same delay time as the initial sequence.of notes.

Observation:
A random period of anything between 1-7 seconds before the delay time changes with the note position. This behavior is observed in both 6-voice and 12-voice modes.

However, in single voice Solo, Legato and Unison modes, the delay time change with note position is instantaneous (and really funky!)

Here’s a patch I made that uses the Note >> Delay Time modulation. It works on my S6 desktop, so hopefully should work on yours too! :slight_smile:

It’s an arpeggiated patch acting over a range of 3 octaves to coax out the effect. Try playing single notes e.g. c3 and you should be able to hear the delay time variation providing a little bouncy accompaniment note or two. I set the delay feedback to the lowest level to keep the desired effect clean. The overall delay level of the patch is set to around 3 o’clock

Compare the rhythmic patterns when playing a note an octave or two above or below c3 e.g. f1 and you should hear more marked syncopation

Turn the delay level down to zero to illustrate how the delay is affecting the overall sound

Change the voice mode to Poly 1 / Poly 2 to illustrate how the intended effect works only in a solo-type mode

Other modulation in the patch: LFO 2 is acting on Env 1 Decay time to provide some filter variation over time, with the filter drive set to level 2, and DDS2 is in LFO mode and acting negatively on the base resonance level

That’s the main takeaway here and it’s been confirmed by support as well:

I tested the modulation routing on my unit today and I can confirm the behaviour you documented. I’ve added this to our bug list for review so that the delay time can be key-tracked with each note you play.

I can think of numerous ways this could be implemented in poly modes as well: last note, lowest note, highest note… just any change to the delay time would be nice…
