This audio effect plugin creates a unique sound with increased sustain and gentle, LFO-modulated vibes. It functions as an AUv3 effect for hosts like GarageBand or as a standalone app for real-time audio input processing.

Highlights
  • Unique sound enrichment
  • LFO modulated vibes
  • Complex resonator system
  • AUv3 plugin for hosts
  • Standalone app mode
  • Gain, Vibe, Depth, Reverb controls

Alien Box is a completely new kind of audio effect that you have never heard before. It makes the sound big and slightly increases the sustain while adding gentle vibes to it. The vibes are LFO modulated and the effect is using very complex resonator system inside. It is modulation effect and you can compare it to flanger, phaser or chorus but it is not like any of them… The app is an Audio Unit Effect AUV3 and can be used inside GarageBand or other AU host apps as an effect plug-in. Alien Box can also run as a stand alone app adding effect to the audio input so you can play your guitar, bass or synth directly three the app if you have the connector to do so. Alien Box controls: - Gain - you can use it increase the gain and sustain - Vibe - main tone and background vibes balance - Depth - controls the modulations depth - Reverb - adds reverb to the background vibes

About

WoodStepper

This app is a versatile music production tool that combines sequencing, synthesis, and sampling. It offers multiple independent sequencers that can be linked, and each can function as a synth. It supports both standalone use and as a plugin within a DAW.

Highlights
  • 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

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.
