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!
- 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
- Auto-triggered by BPM subdivisions or the rate of an LFO
- Manual trigger buttons
- Each envelope generator can have up to 8 destinations
- 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
- 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:
MIDI Mod is not affiliated with any hardware or software manufacturer.
- iOS 14+ Ableton Link network compatibility fix
- Visual feedback when attempting to perform invalid actions
- Improved startup time: only process device specs if there have been changes or new ones added
Ratings and Reviews
Lovely MIDI modulation source
A nicely implemented means of outputting some pretty exciting MIDI modulation variations.
It can take a second to parse the provided guide for some of the more in-depth functionality, but overall if you know how to program a simple LFO or EG and set up MIDI routing/destinations the app is a breeze - just click around! The arp’s fun to play around with as well. Excited to implement into my workflows!
Made by the dev, for the dev.
Nope. This app is a prime example of what happens when someone makes an app for their own personal use, and then as an afterthought, decides to sell it on the app store with zero user friendliness.
If anyone is even looking at this, it's probably because you can't find a midi controller that can do exactly what you need, and you're desperate. Just search the store for "midi script". There's an app that lets you write custom code to create any imaginable midi controller.
Developer Response ,
Thanks for the feedback. MIDI Mod took more than 2 years from initial development to release. For UI design, I imagined having a hardware equivalent, with knobs, sliders, and switches for most functions. I thought other people would be familiar with this sort of design. Along the way, I’ve added new features and UI goodies as a result of user feedback. Its primary purpose is to enhance the modulation capabilities of other devices (hardware and software). It is not meant to be a general all-purpose customizable MIDI controller. There are plenty of apps for that. Sorry if MIDI Mod wasn’t the right tool for the job.
