PocketTracker

PocketTracker is a music tracker in the spirit of LSDJ, LGPT and the M8 — built for Android gaming handhelds with physical buttons, with an on-screen control layout for phones.

Features:

• 8-track sequencer with the classic Song → Chain → Phrase structure
• Sampler instruments: load WAV, MP3, FLAC, OGG, Opus and M4A files
• SoundFont instrument support: SF2 and SF3
• Sample editor: trim, chop, slice, time-stretch (SOLA), pitch-shift, destructive FX
• Sample from video: extract audio from screen recordings (MP4/MKV/WebM)
• 31 step effects: arpeggio, retrigger, pitch slides, vibrato, chance/randomize, tables, grooves, mixer-fader automation and more
• Per-instrument modulation: AHD/ADSR envelopes and LFOs with 10 destinations
• Mixer with per-track sends, true dBFS meters, reverb and delay send buses
• Master bus with OTT-style multiband compression or DUST lo-fi chain, plus limiter
• WAV export: full mix or per-track stems; resample selections into new instruments
• Interface color themes, a theme editor and multiple top-bar visualizers
• Low-latency native audio engine (Oboe); runs well on 1 GB RAM devices

Storage: PocketTracker requests no permissions. The first time you open its file browser it offers a single "ADD FOLDER..." row, which opens Android's own folder picker; the folder you choose becomes its home and is where projects, samples and renders live. You can grant it further folders at any time from the top of the browser, so a sample library anywhere on the device — or a video copied over from a PC — is reachable without giving the app access to everything.

Requires Android 8.0+ on a 64-bit device (arm64-v8a or x86_64).
