Koushion MIDI Step Sequencer app for iPhone and iPad

Koushion is a flexible MIDI step sequencer that integrates with your digital audio workstation software (Live, Logic, Reason, etc.), and iOS MIDI apps (Animoog, NLog PRO, iMini, Sunrizer, WaveGenerator, Alchemy, and more).

Core Features:

- 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 
- 5 playback modes - single, simultaneous, chain, rebound, and random
- 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
- Intuitive tied note entry - Just drag for as many steps as youd like to sustain a single pitch
- Optional Dark Theme - reduces eyestrain when working in low-light environments
- Runs in the background so you dont miss a beat when tweaking your synth parameters
- Uses system resources efficiently
- Timing accuracy is typically ±5/100 BPM over a stable Ad-Hoc Wi-Fi connection, and ±1/100 BPM over a MIDI adapter

Review by Chris Stack of ExperimentalSynth.com

"Koushion has become my go-to sequencer for generating short to mid-length patterns. I just keep coming up with new uses for it. Its a lot of fun with iPad synth apps. I have a lot of hardware synths and Koushion really brings them to life and lets me keep both hands on the synths for maximum expression."
