Nulltrack! It's null when you start and a track when you finish! Nulltrack is a tracker and digital audio workstation app for your phone. A different way to make music inspired by LSDJ and the Dirtywave M8.
Features:
AUv3 plugin support - bring your external synths and effects into your track!
Two built-in synthesizers -- A versatile two-oscillator Basic Synth and a feature-rich Bass Synth.
A built-in sampler -- record your own samples with your phone's microphone, load your own, or use the built-in samples, set loop points, slice, reverse, etc.
Modulation -- Modulate nearly anything with LFOs, AHD / ADSR / drum envelopes, velocity, randomness, and key tracking, filter, panning, and more.
Mixing Features -- track faders with solo and mute, 13 built-in effects, sidechain compression
Sends -- share effects between tracks
Customize your swing/playback with groove tables!
Lock your patterns to a built-in scale!

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
In this update: free-form select, FX editing across a whole selection at once, small ui improvements, and a batch of fixes.
NEW
- Free Select: selections no longer have to be rectangles. Tap "Free" in the selection menu, then tap any cells to add or remove them one by one, or hold a cell for a moment and drag to sweep up several at once.
- Edit FX values across a whole selection at once.
IMPROVED
- The FX list now keeps last scroll position instead of jumping to the top every time.
- UI enhancement: knobs, buttons and panels updated.
FIXED
- The ARP command now works the way arpeggios do in classic trackers: it bends the pitch of the playing note instead of restarting it — so pads and long samples arpeggiate smoothly instead of stuttering — and notes held past an ARP row now return to their original pitch instead of staying stuck on the last arpeggio step.
- The Subtle visual feedback setting now actually shows the same on-beat flashes as full, just dimmer, instead of doing nothing.
- Level meters now respond almost instantly instead of trailing the sound.
- Removing the last target from a sidechain routing no longer crashes the app.
