Track8 is a focused 8-track recorder for iPad, iPhone and Mac: press record, play, done. It is the same software that runs on the Track8 hardware recorder, so it works as a complete recorder on its own, and it opens the hardware's projects unchanged if you own one. No timeline to arrange, no plug-in chains to manage before you can record. Eight audio tracks and eight MIDI tracks, a loop, punch in and out, markers for structure, and a mixer with track and master effects. Every control has one job and sits on the panel in front of you: tap the buttons, drag the encoders, and use the screen in the middle for editing, exactly as on the hardware. What you can do - Record audio and MIDI on eight tracks each, with loop, punch, count-in and a metronome - Arrange with markers: jump, loop, copy and move whole sections - Edit audio and MIDI on the device, with undo - Reshape recordings with the Clipboard Modifier: time, pitch, granular, spectral, filter and voice tools, for audio and for MIDI - Mix with track and master effects, sends and automation - Host AUv3 instruments and effects as outboard gear, wired like a hardware synth or pedal - Use any audio interface, including multi-channel ones, with low latency on recent iPads and iPhones - Map USB, Bluetooth and network MIDI controllers with MIDI Learn - Export mixes and stems to a folder of your choice With or without the hardware Projects are plain files that move between the app and the Track8 hardware in both directions. Record on the go, finish on the desk, or use the app as your only recorder. Track8 is not a DAW and does not try to be one. It is a recording instrument: immediate, obvious and fast, so the idea gets recorded while it is still an idea.

PX1 is a dual-engine FM synthesizer inspired by the classic 6-operator digital synths of the 1980s. Each engine features six operators, 32 algorithms, and full envelope control — giving you everything from glassy electric pianos and punchy basses to evolving pads and metallic bells. What makes PX1 special is the dual-engine architecture. Two completely independent FM voices run side by side. Copy one engine to the other, make subtle changes, then use the Spread control to place them across the stereo field. The result is a lush, wide sound that a single FM engine simply cannot produce. FEATURES • Two independent 6-operator FM engines • 32 classic FM algorithms • Per-operator envelopes (4 rates + 4 levels) • Per-operator pan for detailed stereo placement • Five macro knobs — Brightness, Touch, Attack, Decay, Spread • Copy/Paste between engines for instant layering • Random patch generator exploring the classic FM sound palette • Built-in reverb (Size, Damp, Amount) • Mono, Legato, and Portamento modes • LFO with triangle, saw, square, and random waveforms • Pitch bend range and transpose controls • Key velocity sensitivity per operator • Keyboard rate scaling and level scaling • Operator Key Sync on/off for consistent or organic attacks AUv3 PLUGIN PX1 works as a standalone instrument and as an Audio Unit v3 plugin. Load it directly inside GarageBand, Logic Pro, AUM, Cubasis, or any AUv3-compatible host. Full parameter automation is supported — record knob movements in your DAW and play them back. DESIGNED FOR MUSICIANS The interface stays close to the original FM programming model that experienced synthesists know, while macro controls make it approachable for anyone. Turn one knob and shape the entire sound; dive into individual operators when you want surgical control.
