WoodStepper vs Choral Lab

The WoodStepper is a sequencer/synthesizer/sampler having both audio and midi out. The audio sources can be the track audio, sampled audio (live/track recorded or from file) or the built-in VCO's. The VCO notes can also be set by the Chordulator which finds chord notes in a live stream or recorded track. It consists of 4 independent 8-steps sequencers which can be linked to a 16, 24 or 32 steps sequencer. Each sequencer can independently be set to Synth mode. So WoodStepper can be used in any combinations of sequencers, synths and looper/samplers. Each step can also send 4 midi messages (note on, CC, …) to 2 midi channels. The audio part for each sequencer has a pitch (down) shifter, (Moog lowpass) filter with A(D)SR envelope, saturator, amplitude A(D)SR envelope and delay line which can all be set independently per step. The VCO notes can be set by midi input and WoodStepper has a function to limit the notes produced by VCO + pitch shifters to a specified key and interval scale. The app can be used stand-alone (device audio input and output) or as a plugin in a DAW. The manual can be downloaded from : http://www.woodmansimmaculatemaplesyrupstudio.be/woodstepper/WoodStepperHelp.pdf - IOS plugin type : AUv3 effect, AUv3 instrument and stand-alone app.
 - Has 4 independent 8-steps sequencers.
 - Each of the 4 sequencers can be set to Synth mode, the steps can then be used to automate parameters while playing. - Sequencers can be linked to form 16, 24, or 32 steps sequencer(s).
 - Each sequencer can have a different timing.
 - Steps can be disabled for non 4/4 patterns.
 - Each step can send up to 4 midi messages (+ all previous notes off) on 2 midi channels
 - Audio sources can be the track audio, sampled audio or 3 VCO's (per sequencer).
 - Sampling (audio coming live or from the DAW track) can be armed (per sequencer) with a button or a midi in CC.
 - Samples can also be loaded from file (sample files should be in the WoodStepper iCloud folder) - Each sequencer has it’s own gain, clipping led and brick-wall limiter.
 - VCO’s have the usual waveforms and can be modulated in various ways. - Full polyphonic mode sends 4 subsequent note-ons to the 4 sequencers/synths. - Para-polyphonic mode (per sequencer) sends notes 2&3 to the sequencer/synth VCO's 2&3, giving max 12 voices. - Each sequencer/synth can set the range of receiving midi notes (which allows for up to 4 split keyboard regions). - Each step has a pitch down shifter (sequencer mode only). - Pitch shifters have a glide control.
 - Pitch shifters can be set to a random value (out of a list of scales).
 - Pitch values can be harmonically locked to the Just Scale or the Equally Tempered Scale.
 - VCO + Pitch can be limited to a specified key + interval scale (e.g. C Major Pentatonic) - Each step has a 4-pole Moog Lowpass filter with resonance and ASR (sequencer) or ADSR (synth) envelope.
 - Steps have an additional high-pass filter and a saturation control.
 - All steps have an ASR (sequencer) or ADSR (synth) amplitude envelope and a step gain.
 - Each step has its own delay line with independent timing, feedback, and filtering.
 - Step audio and delay can be panned independently per step.
 - Sequencers can be started manually, started with the DAW transport, start after receiving a midi note or start audio gated. - Sequencers can be stopped manually or after a number of bars have been played. - A “Play 1 Step” button allows to finetune step settings
 - An “All Steps” button allows to set the same parameter value in all steps.
 - Has a global Dry-Wet, Input gain and Output gain control.
 - Presets can be stored in iCloud Drive (makes them available on all your devices).
 - Presets can be switched with Midi Program Changes or with the "Next Preset" button when running. - Major controls can be set with Midi CC messages. - Ableton Link can synchronise tempo, phase and start-stop with other Ableton Link enabled apps.

Choral Lab brings the art of four-part Bach chorale writing to your iPhone. Whether you're a composer, music student, or theory enthusiast, explore one of the most refined harmonic styles in Western music. Harmonize your melodies. Draw a soprano line on the interactive piano roll and watch Choral Lab instantly generate alto, tenor, and bass voices following authentic Bach voice-leading rules — avoiding parallel fifths and octaves, resolving leading tones, and building natural cadences. Browse 410 Bach chorales. Explore the complete corpus of J.S. Bach's four-part chorales with full score display, real-time chord analysis, and playback with rich choir sounds. Two ways to read the music. Switch between a traditional four-part score view with proper notation and clefs, or a piano roll view to see the voice leading clearly laid out across time. Mute individual voices to focus on any single part or study how voices interact. Generate original chorales. Let the app create complete chorales from scratch in any key — major or minor — with realistic harmonic progressions, passing tones, and Picardy thirds. Study chord analysis. Follow along with real-time Roman numeral chord labels as the music plays. Features: • Interactive soprano piano roll with tie support • Automatic SATB harmonization in Bach style • Library of 410 J.S. Bach chorales • Score view with Bravura music engraving font • Piano roll view with per-voice muting • Real-time chord analysis • Choir, piano, and organ sounds • MIDI export • AUv3 plugin — works in GarageBand, AUM and other hosts • One-tap host tempo sync in plugin mode • MIDI output per voice (soprano, alto, tenor, bass on channels 1–4)
