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. ## Key features - 4 independent 8-step sequencers - Synth mode for parameter automation - Sequencers can be linked for longer patterns - Audio and MIDI output - Built-in VCOs with modulation - Sampling from live input or files - Step-based pitch shifting and filtering ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/woodstepper/id1464904963/reviews.md ### 3/5 — Please update sync funtions and looping *2019-12-26* Not for the faint of heart! Great concept but needs further dev. I just got this rather excited but some failings off the bat. - no presets show up in aum preset menu (annoying) - internal preset menu take two clicks to access and is difficult to access. - next preset button but no previous preset button. -transport will sync to aum transport but not actual start on one timing - please add a master measure 1 blink somewhere. Currently recording loops without knowing where you are in the loop messes up. -iphone rendering is messed up depending on orientation and size. Maximize is especially weird. I primarily was excited for 4 independent loopers -looping is always tied to an audio gate instead of an option of self triggering . - sampler wave form display is misleading and doesnt have a now line for playhead. - no immediate looper preset. - add option record arm triggers recording on next defnined length. - first step should be as it is now but also mean that sampling starts on the beginning of step and goes for the defined length. Currently its impossible to start a recording with silence (a rest) Simple work flow. Seq 3 1/4 record arm play kick . Kick loops Seq 2 1 bar record arm play clap on 2 and 4 claps starts on 1 plays 1 bar Seq 3 2 bars record arm record synth Seq 4 4 bars (or5,6,7,8?) vocals for 4 bars. - daw tempo button should be more a latch button instead of momentary. I want the sequencer tempo to follow the daw tempo and lock to the beat always. - please have mute step and skip step possible. A toggle would be nice. This is a cool tool and i’d love for it to be an essential part of my workflow. ### 5/5 — Big Step *2019-06-29* Incredible, powerful app. ### 5/5 — Solid sequencer performer definitely stands out in a crowd. *2019-06-02* I brought this Sequencer, and haven’t been disappointed, if your after something different that does some very clever functions other iOS Sequencers cant manage this is it. It has a very polished design and is a joy to use. Bravo to the developer for adding in all that functionality. ### 5/5 — Clueless people should refrain from reviews... *2019-06-01* Harrumph. This app works beautifully in AUM, Audiobus, ApeMatrix et al. A wonderfully inventive music app, like all from this developer. ### 5/5 — Awesome! Yes it does work in DAW’s. *2019-06-01* It shows up under effects in AUM. This is true of some other apps I’ve purchased lately. Lots of possibilities here. See you later. ### 1/5 — Developer faked Apple w/support contact *2019-06-01* Update: this just doesn’t make sense. The manual mentions DAWs and that it’s both AU and AUv3 as well as stand alone. Then why doesn’t either Audiobus 3 or AUM see WoodStepper as either an AU or AUv3? —- This developer just pointed the Apple Support Contact link to their manual. Support is NOT a manual. That’s called documentation. Right now, this product doesn’t work for me. I checked their other apps and no real support links either. This is the proverbial ‘want to give this developer zero stars’. And it’s not compatible with AUM and Audiobus 3. No instrument nor AUv3, let alone AU. Note to self, don’t buy anything else from this developer. I don’t think I can but I will try to get a refund. ## Frequently asked questions about WoodStepper ### What is WoodStepper?
