Polychord turns your iPad into a chord instrument — a full band at your fingertips. Nine chord circles hold every chord in your key — arranged so the right one is always under your fingers. Tap a circle to hear it, and the ring around it offers the colors: sevenths, sixths, suspensions. Strum across the keys like a harp. You can't hit a wrong note, and you never have to stop and think. Flip on Auto Accompany and a rhythm section falls in behind you: bass and drums that follow every chord change you make, in styles from folk to funk to krautrock. One finger becomes a band. When something good happens, hit record. Loop, layer, and bounce it to audio, or export multi-track MIDI with chords, strum, bass, arpeggiator, and drums on separate tracks, ready for your DAW. In the studio, Polychord comes with you. The AUv3 MIDI-effect plugin puts the chord grid inside DAWs like Logic Pro that support MIDI effects, and MIDI in and out means it can play — or be played by — everything else you own. Whether you've played for twenty years or never learned an instrument, Polychord closes the gap between imagining music and making it. FEATURES • Nine chord circles covering the full harmony of any major or minor key • Chord palettes for folk, jazz, gospel, bossa nova, soul, cinematic, and more • Strum keys with pitch bend • Auto Accompany: bass lines and drum patterns that follow your chords • Arpeggiator with adjustable direction, rate, and octave span • Built-in wavetable synth with ADSR envelopes, filter, delay, and bitcrusher • Record performances and bounce to audio • Multi-track MIDI export: chords, strum, bass, arpeggiator, and drums on separate tracks • MIDI out to any app or hardware; MIDI in to trigger chords from a keyboard • You can even split your MIDI output to trigger multiple instruments at once in DAWs like Logic • AUv3 MIDI-effect plugin: play the chord grid inside your favorite host • AUv3 works in DAWs like Logic Pro that support MIDI effect plug-ins Polychord is a one-time purchase.

SampleScape is an AUv3 plugin for use in your favourite DAW such as AUM, Cubasis, GarageBand, Logic or Loopy Pro. SampleScape is an innovative sample-based instrument for building complex evolving soundscapes. You can create a sequence of steps, each step being either an individual sample or a collection of tuned samples which we refer to as an instrument. Each step allows you has controls how it is played back, either as a traditional sample or via granular synthesis. You can control transition times, fade times, transpose, pitch, glide, level, pan, vibrato, tremolo at each step, and together with a 3 mode morphing filter and integrated effects you can create a constantly evolving and complex soundscape. SampleScape also has the ability to map any incoming CC controllers to a large number of internal knobs, sliders, switches etc. for fantastic automation possibilities. Our build in Auto Sampler makes recording samples from other instruments so simple. You can use this to expand the library of more than 114 pre-build instruments. SampleScape also has a configurable randomisation feature which can piece sequences of instruments together to create new sequences at the press of a button. Need more samples, simply drag and drop SF2 files into the Sample Library to extract all the samples. The Sample Library also lets you configure and reference a remote folder on your iPad. This is useful if you already have a sample library located on your iPad.
