Instant access to your entire sample library.

Drop a folder of samples onto Protoform Lite and it becomes a pool. Now stop searching for the right sound the usual way: roll the dice and let Lite surprise you with a random draw from your pools. When a sound catches your ear, flick through its neighbours in the same folder with the arrows. Or drag in one specific sample when you already know what you want. Whatever you land on plays across the keyboard right away.

Free, pay-what-you-want.

Three ways to play a sound

The playback mode changes what you get out of the same sample.

• ONE-SHOT is the predictable one: every note plays the sample from its start point, just as you would expect.
• LOOP repeats a region of the sample. On rhythmic material, a loop length that doesn’t match the bar and a moving start position turn it into a tool for finding new sequences. On atmospheric sounds, add position jitter and one sample spreads into a cluster of textures.
• CONT runs the sample as a continuous tape, and each note opens a window onto wherever it is. Layer a few instances and loop them, and the result keeps shifting in ways you wouldn’t get by playing it straight.

Lite Factory

A free companion pack: 75 presets and 178 sounds from across Sample Spektrum, one pool per source pack. It comes as a separate download next to the installer. Drop it on the Lite window to install it, or skip it and point Lite at your own folders.

Shape it and keep it

• Start position with per-note random jitter, an envelope with adjustable curves, pitch, pan and velocity.
• Tempo sync for loops with a BPM in the filename.
• Loop start, length, direction (forward, reverse, pendulum) and fade.
• Two views: Orbit, the sample as a ring, and Standard, a classic waveform. Waveforms take the pool’s colour or show the frequency content, and LAYERS turns the low, mid and high bands into an animated form that pulses where the sample plays.
• POLY for chords and overlapping notes, or MONO for one voice.
• Presets that store the whole instrument (sound, settings and pools), stepped through from the top bar.
• Drag the current sample straight into your DAW.

Where it fits

Lite is the single-sound side of Protoform, which fills a 16-slot kit from the same pools, sequences it and prints every slot to its own audio stem. Both use the same pools and library folder, and full Protoform opens Lite presets as one-slot kits.

Requirements

• VST3 and AU, macOS 12 or later (Apple Silicon and Intel).
• Windows 10/11 64-bit VST3 build included. macOS is the officially supported platform: I have no Windows machine to test on, so the Windows build comes as-is, with no guarantee it runs on your system.
• Lite Factory pack: about 600 MB of disk space (optional).
• No licence key, no account, no internet connection needed.
