Description

Octachron is a flexible 8 Track MIDI Sequencer with rich modulation and sequencing capabilities. It is optimized for drums but also fun for experimental melody lines. It works standalone or as AUv3 AudioUnit in your favourite iPad DAW (like AUM, Cubasis, Beatmaker, ApeMatrix or Nanostudio etc.).


“An exciting MIDI sequencer with advanced features” (Synth Anatomy)

“Particularly the probability parameters are a lot of fun” (Amazona)

“Octachron controls just everything with iPad” (Gearnews)


*Please notice: Octachron is a MIDI sequencer and does not create any sound of its own*

We believe in specialization, so Octachron is focused on in depth MIDI sequencing. Control your favourite iPad drums like Ruismaker or MV08, synths like Zeeon or Model D or any hard- or software MIDI instrument with it.


*iOS 11 or higher required. If used with a host software, this has to be compatible with the MIDI AudioUnit standard.*

Ugh so close to perfect

This is the closest thing I’ve seen to a perfect step sequencer on iPad . With minimal work it could be perfect. But it’s missing 2 key features that actually make it worse than a lot of sequencers out there for the user

1. No note length. Makes it useless for anything but plucks and drums. Just adding a gate modulation row would make me use this sequencer above all others. And would raise this review to 5 stars

2. Only 1 octave. This would be harder to fix but also less important imo

In any case this is so close it makes me sad every time I open it.

Extra cool thing would be midi recording.

Hey DSB, thank you so much for your nice review of our MIDI Drum Sequencer.
And thank you also very much for your suggestions. They definitely make sense. Though we decided to focus on Octachron being a drum sequencer. But we collect all the feedback and prioritize it for further updates.
Keep enjoying Octachron and best greetings from Munich!

Love this step sequencer but it is buggy!

Ok so i figured out how to midi route this step sequencer with EG Pulse since i can drag and drop my files from files app into EG Pulse very conveniently. All first 8 pads are routed and everything is great but this step sequence keeps repeating notes that I don’t have any repeat on. Specifically with the first slot which i have my snare preset to and it just repeats the snare hit when I don’t want it to. Second bug is for the second slot and the problem i have with that is my kick just mutes when I turn song mode on so i can get 64 steps. The first 32 steps for my kick, which is the second slot, just does play and it unmutes for the second pattern. Super frustrating when this step sequencer is suppose to speed up my workflow.

Hey juanthedon888, thanks for your review of our MIDI drum sequencer and sorry to hear that. We tested it again and especially in AUM it went very well. Do you still have these issues?

So good

If you want to sequence drums in IOS, this app is the one to get imo. Straightforward but with a lot of good variation options (probability, polymeter, patterns). It's so nice to control various tracks at once on the same app.

For the price it's absolutely worth it. I do wish that it was easier to switch between the parameter being automated (not easy to change live). Also not being able to set all automation steps to the same value makes automating pitched drums hard. But it's still a great app.
