Sequencer restarts unexpectedly on variation change

Antimon

Problem: When assigning the length of a sequencer to a morph knob, changing variations will cause the sequencer to restart at position one, even if the morph is at the exact same position in both variations.

Open the submitted patch and try switching between variations one and two. Notice how the sequencer restarts although there is no connection to Lp or Rst, and the length is the same (since morph 1 is at the same position).

The G2 will restart a sequencer whenever its length is changed (I don't like this behavior either, although it might not be considered a bug), so I'm guessing that the code assumes that if the length is morphed then it will probably change whenever variations change.

The reason I ran into this was that I was trying to make a general big sequencer patch for my Electribe ESX-1 that could quickly switch tempo signatures (e.g. length=16 or Length=12) with a morph knob. I couldn't understand why the thing kept restarting when I switched variations. Now I'll have to click manually in every damn sequencer Mad

This is a bug IMHO. The NM1 did not have such behavior, neither does an analog sequencer (in a Moog modular, or a Roland System 100).

The only time a sequencer should restart is when you reset it explicitly, or the current steps exceeds the loop length (if loop is turned on).

This "bug" wreaks havoc in a live situation, when you are trying to tweak sequencer lengths, or in your situation change variations.

A workaround is to use a 2nd gate sequencer, and use it's gate output to reset it and the 1st sequencer at the desired step length. Sequencer 1's loop setting should be turned off.

Something like this? You set the sequencer length by moving the set square in the SeqEvent module.

I would like to stress that we are talking about two different bugs here. The original one (sequencer resets when you change length) I've personally learned to live with.

The second (that I wrote about in my first post in this topic) is that in some cases the sequencer restarts when you change variation even if there is no change in length. This happens if you have assigned a morph to the length. When you change variation, the sequencer restarts even if the morph stays at the same value. This is a bug that cannot be justified in any way, IMHO.

I see. that is bad. I hope this is fixed at the same time as the loop length reset issue.
