Updated Koushion 4.2 Now Available

koushionDeveloper Ian Wagner let us know that Koushion – his step sequencer app for iOS – has been updated to version 4.2.

Here’s what new in Koushion 4.2:

  • Per-step gate and velocity editing
  • Embedded app manual viewer for offline reference
  • Minor UI tweaks to improve accessibility to frequently accessed controls


  • 16 steps per scene
  •  8 scenes with independent MIDI channel, key, quantization, and playback mode (combined, this makes for up to 128 steps per layer in chain mode)
  • 16 layers of scenes that act like individual tracks
  • MIDI clock send/receive
  • 4 playback modes – single, simultaneous, chain, rebound
  • Scale – switch between any major, minor, pentatonic, or chromatic scale
  • Adjustable step quantization – 1, 1/2, 1/3, 1/4, 1/6, 1/8, 1/12, 1/16, 1/24, and 1/32
  • Quantized scene switching
  • Tap to set tempo – great for syncing with a live band
  • Per-step velocity, gate and CC sequencing
  • Monophonic drawing mode – only allows one note per step; great for programming leads
  • Optional Dark Theme – reduces eyestrain when working in low-light environments
  • Runs in the background so you don’t miss a beat when tweaking your synth parameters
  • Timing accuracy is typically ±5/100 BPM over a stable Ad-Hoc Wi-Fi connection, and ±1/100 BPM over a MIDI adapter
  • Compatible MIDI Connections:
    • Automatic integration with other apps via Core MIDI virtual ports
    • Control of external MIDI devices via Core MIDI-compatible connections such as the iRig MIDI and Alesis I/O dock
    • MIDI over Wi-Fi via Core MIDI network sessions (warning: unpredictable latency)

Koushion is available for US $7.99 in the App Store.

  1. Really looking forward to trying out the new per-step gate and velocity sequencing on this update. I’ve got a patch on my Voyager that gets a nice snap to it at certain velocity levels. Being able to dial that in exactly is going to be a lot of fun, especially combined with the MIDI CC sequencing features that were added a couple months ago.

  2. I just wish developers would let us have more than 16 steps in an individual pattern. 128 or 256 would be ideal. Working with chains just seems like an unnecessary step for a longer pattern.

    1. Agree 100%.

      A 4-bar/64-step sequence, like all the old Electribes could do, seems like the minimum for what you’d want in grid sequencer. Otherwise it gets pretty fiddly to build up songs.

    2. Thanks for the suggestions! Flipping a layer to chain mode allows you to sequence up to 128 steps. I really like the idea of having variable sequence length (so you could play solo, or even chain together sequences of any length you desire). This would allow for some really interesting possibilities. Look for this in a future update 😉
