OCTACHRON MIDI Drum Sequencer AUv3 by Markus Teufel

Just from looking at the screenshot… there is a big difference between note division and shortening beats/bar. With Octachron you can have your 16 beat track run for 15 beats instead, so a beat gets dropped every time it plays. But those beats are still landing in the same time division. It’s not true polyrhythm as I understand it. If you divide your 16 beats equally by 3, those beats are going to hit on a different rhythm than your 4/4 rhythm.

That's not the alternate setting in the Manual we are discussing, though, per the original question of whether Octachron could do polyrhythms (TasTax answered yes).

The Manual says under Modulation:
"Track Length allows you to change the length of each track independently from the others and create polyrhythms")

And as TasTax also said "Track length... is for shortening single tracks in comparison to others, so that hits appear at different times compared to the others each loop. This is what we call polyrhythm."

Our discussion digressed into achieving the specified note values which are building blocks of certain polyrhythms (listed only by way of example as others seem obviously possible); more concretely what I was hoping Tas could help flesh out is what values playing against one another polyrhythmically are or are not possible in Octachron and precisely how to set it up to the extent that this is possible.

I was able to do all the basic Gary Chaffee sticking pattern stuff in both Patterning (after consulting with the dev, in the manner explained above) and obviously Beat Scholar (in that case in a simple manner right out of the box so to speak). This sort of thing isn't academic for me but very important to my own compositional style and also, of course, to a whole s&*tload of contemporary music (and a lot of older stuff too). Also hoping to flesh out metric modulation and polymeter later on.

I think Octachron can do at least some of this stuff for sure; I'm just a little fuzzy about exactly what (and what not) and about translating clock times into my more "comfortable" forms of music speak and so on.

Hey everyone, this is so cool. I love this nerdy discussion around rhythms and what can OCTACHRON do! The idea behind the clock dividers per track was to achieve this type of rhythms! I made a short video on how to achieve this. Please excuse the bad audio, hope its still helpful!

Cheers

@TasTax - The issues with GR2 transport are all fixed now, thanks so much!!

While on the subject, having the option for non 4/4 would be cool. You can just do them over 4, not the whole gamut, tho preferable. The majority of Octachron users are electronic musicians, so they are going to be writing in standard time, but I use it to power one shot as my drummer in a metal band and I often use odd time signatures if possible it would be cool to have that option in ochtachron

Also @TasTax , if you might be able to throw in an option for some rock generated, that would cool too, thanks for your time and for listening to the users

Hello, I couldn't find the answer in the whole thread:
How can I save a preset in Standalone Octachron, and find it when I load it in an Auv3 Octachron (inside a host?)

jsmonzani

@reinerspass Ive just noticed that adding tracks (beyond the 8 default) wrongly assigns them to channel 0, hence producing no sound. When inspecting the track properties and tapping the + button of the channel, it also jumps from 0 to 2.

Also happening with the Generate scale function.

It was previously working and assigning channel 1 to new tracks by default.

reinerspass

Hey @5alien currently its now possible to sync presets between AUv3 and the standalone app.It's on our list, but its not straight forward. Sorry about that.

@jsmonzani Yeah, thanks for reporting, I've also noticed that, will fix asap.

Did octa lose the ‘swing grid’ setting?

Thank you for your answer, duly noted. I'll search for a way to export/import my presets.

No? At least not for me ...

There used to be another dial there, it’s still in the manual but it’s disappeared from the app it seems.

No “Swing Grid” dial on mine.

Slush

No, no Swing.

reinerspass

Hey @Cỗirácâyỗirpthui, you're correct we removed Swing Grid feature, or rather, with the last update some parts of the app where completely rewritten, und we decided not remove complexity a bit on the swing grid side.
Is it something you and everyone just noticed or are you actually missing this feature. If so what are you using it for?
Cheers Markus

Hey everyone, we released version 2.1.2!

This update addresses several bugs and improves performance:

• Broken MIDI/parameter control
• Incorrect MIDI channels when generating scales
• Unreadable labels in the modulation selection dialog
• Reduced usage of DSP resources

Thanks so much for your continued support!

Thanks a lot for the update.
I do appreciate the DSP fix. Much less resource usage on my iPad 9.

Thanks for another great update.
I love Octachron, but I’m struggling with two things. I use it in Loopy Pro and want to use widgets to switch between patterns. I encounter these two problems:

1) I can switch patterns only once. After that, the pattern won’t change when prompted through the widget. This might be a Loopy “problem”, I’m not sure? I choose Octachron’s own AU parameter option for changing the pattern in the widget, can’t think of other ways - and, as mentioned, it DOES work on the first try.

2) I like to have some patterns with fills, and then switch in the middle of a pattern to get some fills action. So, I choose Instant Pattern Switch in Octachron, but when I switch between patterns in the middle of a pattern, there is a flam effect, as if they’re not doing a “clean” switch.

Hope anyone has a suggestion for a solution, if the descriptions make sense at all? 😃

Are you sending Note On followed by Note Off, or CC value 127 followed by value zero? That may be required before selecting another pattern.

Yeah it's the same with Baby Audios Transit. I need to send a 1 followed by a 0 so that the button resets to be able to re-engage the effect. Maybe try this with Octachron as well?

reinerspass

@uncledave Yes, @oscillotus is correct, you can just use Press and Release states for it, where Press would set Value to true, and Release to false. Somehow the app has to detect a change.

Goodwin78

Ah, great! Thanks, everyone!
