FOR MELODIC INSTRUMENTS GENERATE VARIOUS SCALES IN ALL KEYS
OCTACHRON is optimized for drums. But it also supports standard melodic scales like major, minor and also more unusual ones like mixolydian, phrygian and more ...
Ive been using this amazing sequence for a long time, its had several amazing updates to enhance the abilities of this great application. Its simple and easy to use but with complex features for all your sequencing needs. It has offset, probability, repeat, velocity, mutate, random generator, presets for so many drum apps and hardware, and much more. Can play notes or send CC data as well. A brilliant, well crafted app, that i would highly recommend to anyone looking for a great AUv3 sequencer!

Thank you very much for your nice feedback! Glad you like our MIDI Drum Sequencer. Keep having fun with it and stay tuned for updates!
Love this step sequencer but it is buggy!
juanthedon888
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?
I love the app, but the latest update has broken my projects
Obis11
The latest update has made it so a majority of my patterns within AUM sessions, the patterns in octachron have disappeared. This has completely stopped my latest projects that include octachron. I’m not sure if it’s because these were larger sessions, but before the latest update these projects had no issues. I tried contacting the developer on one of the other platforms directed to by the site and was unable to get a response, so I’m posting here. Also I would love it if there was the option to add more patterns.
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.
