Koprod
Mac app Make a song
Studio

Everything a song needs, in one window.

Koprod pairs the simplicity of BandLab with the workflow of Ableton Live: jam with clips in the Session view, build the song in the Arrangement, edit notes with Live 12-style MIDI tools, and mix with sends, returns and a master chain.

Views

Two ways to build a song.

Arrangement
Arrangement view with sections and clips
Sections, a loop brace, drag, copy (⌥), resize and split clips; dropping a clip on another overwrites it, as in Live.
Session
Session view clip grid
Launch clips and scenes quantized to the bar, then record a performance into the arrangement.
Editors

Edit every note.

Piano roll
Piano roll with scale highlighting and notes
Scale highlighting, a draw tool, velocity and per-note chance, and 31 MIDI tools.
Drum sequencer
Drum step sequencer
Steps with accents, velocity and chance, for synthesized and recorded kits.
  • Audio clips with warp, transpose, gain and offset.
  • MIDI tools: quantize, humanize, legato, staccato, accent, crescendo, transpose, octave and scale shifts, invert, fold, harmonize, chord stacks, strum, arpeggiate, double- and half-time, reverse, ornament, recombine, vary, thin, chance, continue and duplicate.
  • Recording of MIDI from the computer keyboard (A–K row) or any MIDI controller, and audio from the microphone, with count-in, metronome and latency compensation.
Sounds

Instruments and effects.

EQ, compressor, reverb, delay, chorus, phaser, distortion, filter, lo-fi, limiter, utility and tremolo, plus chain presets: Vocal Enhancer, Punchy Drums, Lo-Fi Tape, Wide Pad, Bass Glue and Lead Space.

Aurora Synth

Virtual-analog: two oscillators with unison and detune, sub and noise, three filter types with envelope, two envelopes, LFO, glide and mono mode.

Prism FM

FM with two modulators for electric pianos, bells, mallets, basses and plucks.

Pulse Drums

Seven synthesized kits (808, 909, Lo-fi, Trap, Acoustic, Techno, Afro) with tune, decay, tone and drive. Drop your own sample on any pad.

Sampler

Play any audio file chromatically, with root, tune, start, loop, envelope and filter.

Acoustic

26 recorded instruments with dynamic layers, round robins and articulations.

Device chain
Synth device with oscillators, filter and envelopes, followed by effects
Every parameter is a knob you can turn, automate from the Producer, or set over MCP in natural units like “1.2k” or “−6 dB”.
Recorded instruments

65 recorded instruments.

Multi-sampled with dynamic layers (five on the grand piano, up to four elsewhere), alternating takes on repeated notes, seamless sustain loops and per-note levelling. They load only the notes a song uses. Ranges below are the recorded ranges; notes slightly outside are stretched from the nearest recording.
