ForumsSoftware ← you're a crafty one randy..?!

this is either a great 'easter egg' feature or its a great bug!
i've been messing with the unison mode with the 'voice' patched into 'offset' and using the seq to create one-note chords etc. and am getting some incredible sounds. but something i just noticed was that the unison detune amount can be altered with the last fader in the seq. so for a 4 note unison chord (with offset input of 1 tick on the dial so 4 voices are playing at once), the number 4 slider will affect the de/tuning of the unison notes! is this a sneaky easter egg behaviour, or are things goin weird at my end in a really cool way ?

[edit] ok it only happens when making a preset from scratch using 'default' preset and only while using the vst version (au works as expected) so its some kind of really cool bug i guess. i can't copy-paste the preset here as i'm still using a demo, but i can post a screengrab if anyone wants to try out the 'quirk' ?

[edit2] ok, loading up the preset 'aalto techniques > seq chord' will show you how its patched, BUT this preset doesnt do the unison detune trick on the last slider, even tho all settings are pretty much identical. but making it from sratch still shows the same odd-but-cool behaviour...!?

i'm sure this makes no sense to anyone but me, but heyho...

It doesn't quite make sense to me what you're talking about, because I don't know what you mean by "affect the de/tuning of the unison notes". Maybe the difference is where the sequence is within the step. It's kind of complicated to explain without pictures. I'm trying right now in the manual, so maybe stay tuned for a full explanation. The outputs with 0 steps in a sequence and 1 step will be different, and if you run the clock, then stop it, it will be frozen in the middle of a step and you can see different results.

no easter egg type thing is intended. and if vst and au work differently, that would be a bug. can you tell me a sequence of steps to do, that gives different results for the VST and AU versions? You could start from default or any factory patch.

yea i missed out a few details in my OP. sorry - it was late!

i've just done a v.short video. link is:

there are no names, comments or tags associated with Aalto so all good.
let me know when you've had a look, and i'll take down the vid.


Uh, I see now but I have no idea. That's very strange. Thanks for making the video. I'll investigate soon because, if there's some behavior I don't understand, maybe it's a clue to one of the other bugs happening.


It's a little weird but not that weird. I made a mistake by believing what you wrote in the text in your movie. Only one voice is detuning a bit when you change slider 4, not all of them. To verify, turn all the other faders to the same note, and hear the increased beating that results for turning up fader 4.

What's happening is that one voice gets mostly the signal from fader 3, with a tiny bit of fader 4 mixed in. This is because of the way the interpolation works. When the rate is 0. and has never been changed, the fractional part of the step is 0.0001 or something like that. If you set the # of steps to 1 and turn the rate up, you should get more obvious behavior.

I don't have too much time now but I'll try to explain better in the manual.

now its my turn to be confused! not sure from your reply whether you mean its a bug or a feature..?! the odd behaviour doesnt bother me but there are some irregularities in the way it works. eg:

try the preset 'aalto techniques > seq chord'

as you can see, its patched the same way as my vid example, but the difference here is that all 4 sliders in the seq affect the tuning of the 4 voices FULLY, whereas with the newly created patch example in the vid, the last slider only partially affects the tuning of the previous slider's voice.

strange things are afoot!
i'll leave it with you anyway - still having fun here


Think of each sequencer's position as a continuous number with a fractional part, not just the integer step number. The light just shows the integer position. But depending on where the actual fractional position is within the step, you can get different results.

This is what the difference is between your example and the preset. If you change your example so that the number of steps is 1 and rate is nonzero, you will get the results you expect.

ahhhh ok, yea changing the rate brought all 4 voices back under control. i don't think i fully understand your explanation but at least i know how to change it now! thanks for explaining. it'll sink in one day :)

oh and good luck writing that up in the manual hehe..
