Metropolix - delayed scale change via mod lane?

Hi, I’m using a Mod Lane to switch between User Scales, and the issue I’m running into is that when the Mod Lane = +1 (switching to User Scale 2), the first note of the pattern is still “stuck” in User Scale 1. This results in the first note of what should be a different chord being part of the “old” chord. I hope that makes sense.

Here are my settings:


  • Stages = 7
  • Pulses = 16
  • Div = 1 (both Clock and Pulse Count)
  • Gate Length = 15%
  • all other track settings are Default

MOD LANE (Mod Dest: Scales (User)

  • Stages = 4
  • Pulses = Auto (I tested with Pulses = 4 and no effect)
  • Div = /16

This is likely user error. Any thoughts on how to have the Scale change happen so that the first note is in the “new” scale?

If I understand you correctly, I had the same problem but while switching between two different presets that used different scales. Here’s my post:

From my post: “The glitch is that when Metropolix switches between presets, it gets the first note of the preset wrong on the first pass…”

Yes actually now that you mention it I had the same issue when trying to do this with presets (including preset chaining)

I should also say I’m on the latest firmware.

I’m trying to change root notes as well. The scale/root change is B Lydian (User Scale 1) to E Major (User Scale 2) and the first note of the sequence is the lowest position on the slider, and I have that set to the be Root (rather than C in the Setup Menu)

Ah, yes, now I’m remembering, my issue wasn’t changing scales, it was changing the root.

I will log a bug report and note to check it out. If it turns out to be an issue, I don’t have an ETA right now. Thanks for the heads up.


Understood, thanks for the update!

I’ve confirmed this bug, it’s specific to the Bottom Pitch setting, If it’s on C. It only happens on specific scale combinations and if the new scale has a different root note. I’m working on a fix now. Should have a small bug fix release this week sometime.
