Is it possible to get MF-104M synced repeats for eternity?

Post by stephan___martin » Wed Sep 23, 2020 2:03 pm

Recently I bought a used Moogerfooger MF-104M and I have been trying to send some sounds into the MF-104M and get them to repeat (and evolve) for eternity, and create some crazy cool sounds. However, even though I have it synced via MIDI to Ableton I find it hard to get the sounds from MF-104M and Ableton to sync over time, and it feels like the moogerfooger delay is drifting a bit. Perhaps somewhere around 0.05 bpm when having the daw clock at 120bpm (my guess after inspecting the recordings). Enough for it to really feel out of sync after about 15-30 seconds.

Is this just how dBucket delays works, and I should pick another tool for the job?

I have also been experimenting with a Strymon Timeline (using the digital dBucket algorithm), and I think it also drifts a little over time. However, the digital delay algorithm on the Timeline is perfect on time for very very long time though.

If there is no synchronization between them, no two free-running oscillators will stay in synch for long. Even crystal controls with only several part per million error will shortly diverge.

I don't know what "synced via MIDI to Ableton" means, if may obviate what I just said.
VoyagerEB, Minitaur, LittlePhattyII, 4xSlimPhatty, Sub37, MF[2x101,2x102,103,104M,105,105B,105M,2x107,108M], 3xCP251, XV351, MP201;
System 55 and Minimoog clones, personally modified to bring them closer to OG spec(s).

I guess we're talking midi sync here.

The answer is basically a no.

When a delay is midi synced it's never perfect, because midi is inherently inaccurate.

As log as feedback isn't full up, you never notice.

Once you have repeating audio, then to stay in sync you'd have to hardsync the audio, checking for it going out and then when it's noticeably out you'd need to shift the audio in some way to keep it in line.

That's going to cause a glitch in the audio, and if you're feeding audio in at the time that glitch gets recorded.

So the long answer is....not without compromise of audio.

That's for every delay ever, not just the MF-104M., and it's a constant issue with loop pedals.
