MIDI Mod

This app provides a powerful set of modules for generating and routing MIDI modulation signals. It features a vast mod matrix, multiple LFOs, envelope generators, and an arpeggiator to control various parameters internally or externally. Preloaded mappings and easy MIDI Learn simplify integration with other devices and software.

Highlights
  • 32-slot mod matrix
  • 4 LFOs with user-editable waveforms
  • 3 Envelope Generators (ADSR, 4-stage)
  • Arpeggiator with chord memory
  • MIDI Learn for CC and Sysex
  • Over 60 preloaded device mappings
  • Internal and external modulation routing

MIDI Mod is a set of modules designed to be used as modulation sources that send MIDI to various destinations. In addition, the majority of MIDI Mod's own parameters can be modulated internally. For example, the output of ENV 3 could be used to control the rate of LFO 1. The output of LFO 1 could be used to control the playback velocity of the arpeggiator, and so on. MIDI Mod features a massive 32-slot mod matrix, which can be used for routing internally and externally to any number of things, including hardware devices, software, and other apps. The sheer number of possibilities can be daunting, but don't let that stop you. To make things less overwhelming, MIDI Mod comes preloaded with parameter mappings for more than 60 devices and apps, including some of the most popular devices on the market today. More are being added, and if a mapping doesn't exist for your device yet, fear not. It's very easy to create routings just by entering a CC number or via MIDI Learn. MIDI Learn even works with Sysex! TL;DR 4 LFOs - All the classic wave forms, plus 1 slot per LFO for a user-editable waveform - Key retrig and LFO delay - Slow and Fast modes, up to 40 Hz - Rate sync to BPM subdivisions - Sync any LFO to the rate of another - Each LFO can have up to 8 destinations 3 Envelope Generators - 2 ADSR with delay and hold - 1 4-stage with individual levels per stage, plus delay and hold - Loopable - Auto-triggered by BPM subdivisions or the rate of an LFO - Manual trigger buttons - Each envelope generator can have up to 8 destinations Arpeggiator - Stores up to 16 notes - Standard features, including Octave Up/Down, Note Repeat, Gate Length, Clock Subdivision, and several playback patterns - Velocity decay/fade feature - Chord memory with polyphonic playback - Create rhythmic patterns by turning on/off individual notes in latch mode - Auto Transpose Sequencer allows automatic transposition of the entire note sequence up to 16 steps. Think of it as a sequencer of a sequence - Arp note on and note off can be used as a modulation source (up to 8 destinations) - Note messages can be suppressed so that only modulation takes place 32-Slot Mod Matrix - Destinations can be internal or external (only limited by the amount of devices/software/apps you have) - Internal destinations include just about every knob and fader within MIDI Mod - Over 60 (and increasing) included device control mappings, making it easy to simply select your device, and the name of the parameter - Destinations can be MIDI CC, Sysex, or NRPN - MIDI Learn for destination select (CC and Sysex only) - Individual range controls for each mod slot (If the destination has a range of 0-63, you could set the min to 5, and max to 55, for example) - Destinations also include pitch bend, aftertouch, mod wheel, and even MIDI note - Every mod slot can have its output inverted (negative) - Mod sources include the 4 LFOs and 3 Envelopes, Arpeggiator note on/off, Aftertouch, Velocity, MIDI Note (keyboard tracking), Modwheel, Pitchbend, Expression, or any CC of your choice Other Features - Quick access on-screen keyboard for entering notes/playing devices - Configurable Max LFO Delay and Envelope Phase times, up to 40 seconds - Aftertouch delay, which filters out incoming aftertouch messages until the desired time after key press - Max MIDI messages per second (some devices are better at handling audio rates over MIDI than others) - MIDI clock send and receive (sync) - Analog sync out (sends out an audio pulse in sync with the current tempo) - Ableton Link for solid tempo sync with other Ableton Link devices - In app User Guide Some features of this app are made possible by the AudioKit framework Current list of devices and apps with defined parameter mappings: https://eokuwwy.blogspot.com/2019/05/device-parameter-mapping-list.html MIDI Mod is not affiliated with any hardware or software manufacturer.

VADrumSM is a standalone mobile drum machine featuring a virtual analog drum synthesizer and a step sequencer. The virtual analog drum synthesizer supports AUv3 Audio Unit Extensions, which allows users to use the drum synthesizer inside of AUv3 hosts, such as Apple’s GarageBand®. The sequencer supports Ableton Link. You can synchronize the sequencer to Link-enabled apps and devices. Drum Synthesizer The drum synthesizer is inspired by the iconic analog drum machines of the 1980’s and features 21 drum voices. Sounds of the each drum voices are synthesized in real time by using component level modeling. Pads Pads function as XY controllers, XY controllers with trigger, or drum pads. When using pads as XY controllers, destination can be selected from tone/decay, level or pitch. Step Sequencer The step sequencer is designed to be intuitive and easy to program drum sequences. It is a 16 step sequencer and it has 3 accent level for the each step. Double hit mode allows to program two 32nd notes instead of the one 16th note. There are 4 patterns and can be chained to create 4 bar loop. There are 6 variations of swing, which can be applied in real time. Parameter Automation All XY parameters (tone, level and pitch) and voice switches can be automated, that gives a whole new sonic possibility. MIxer 17 output buses, including a mix output and 16 instrument outputs of Drum Synthesizer can be routed to main output and 4 aux mixers. AUv3 effects can be inserted to each channels. Sum of the 4 aux mixers outputs can be routed to Audiobus’s second output port. FEATURES Drum Synthesizer - 21 analog modeling drum synthesizers, including 2 bass drums, 2 snare drums, 2 sets of low, mid and high toms, low, mid and high congas, rim shot, claves, hand clap, maracas, closed and open hi-hats, cymbal and cowbell. - 3 Layers of 16 XY pad controls (Tone, Level, Pitch) - Drum Pads Mode (Pad) - Trigger Mode (On / Off) - MIDI input (mid note events only) - Output mix signal and all instruments signal - Support Audio Unit Extensions (AUv3) Step Sequencer - 16 step sequencer - Variable Pattern Length - Parameter Automation - Swing: 6 variations - Accent: 3 level - Double hit: on / off - Pattern: 4 patterns - Pattern Length: 1 bar - Loop length: 1 bar or 4 bar - Note length: 16th or 32nd - Record quantization: 16th - Chain mode: on / off - Tempo: 20 BPM - 999 BPM - Support Ableton Link * Ableton Link requires Wi-Fi connections. Others -Support Audiobus (main output and aux output) -Built in User Guide
