- 2 LFO/VCO oscillators
- Custom drawable waveforms
- MIDI CC control
- Tempo sync
- Envelope generators
- XY pad control

CV Mod is a 2 LFO/VCO Oscillator Module meant to be used with modular or semi-modular synth hardware. Simply connect the headphone output of your iPhone or iPad to one or more CV or audio inputs on your hardware. To get the most out of this module, use a stereo breakout cable to separate the left and right audio channels. Just like that, you now have 2 additional LFOs or full range oscillators added to your rig! CV Mod can also send out signals via a connected DC-coupled audio interface. With Audiobus 3 and Inter-app audio support, you'll have an easier time routing CV Mod's outputs to wherever you need them to go. In the spirit of modular synthesis, you have complete control over each oscillator’s parameters via external MIDI. You can also modulate one oscillator’s frequency and phase with the other oscillator’s rate and depth controls. With two drawable wave table editors, you can create whatever crazy wave forms you like, unleashing a vast sea of possibilities. Instant grit! Intuitive controls via the main faders, XY pad, or MIDI CC make this an incredibly easy way to add more modulation and sound sources to your gear. Download now and have some good old-yet-new-fashioned creative fun! Key Features: 2 Oscillators that function as LFOs or sound sources with 5 frequency ranges: 1 Hz, 4 Hz, 40 Hz, 120 Hz, and VCO mode (full range). This wide set of ranges allows for ultra slow ambient filter sweeps and rip roaring ring-mod madness Choose from 8 different waveforms: Sine, Triangle, Sawtooth, Reverse Sawtooth, Square, Random, and two user defined shapes Wave Table grid editor allows you to draw 2 custom waveforms Each oscillator has its own envelope generator, which can be synchronized to subdivisions of the current tempo or the rate of one of the oscillators Multi-touch control of each oscillator’s rate, depth, and phase with easy to use faders Fine tuning control of each oscillator, + or - one octave Separate glide controls for each oscillator, with a configurable maximum glide time of 120 seconds! MIDI Keyboard control of an oscillator’s frequency allows you to play notes and use this app as an additional sound source in VCO mode Duophonic mode allows you to play two notes at once when both oscillators are controlled by MIDI keyboard in VCO mode XY Pad allows you to control up to 3 parameters, with the Z-axis mapped to touch pressure (if your device supports it) Tempo Sync feature that constrains each oscillator’s rate to subdivisions of the current tempo, when operating in one of the LFO modes Rich MIDI implementation allows you to control all oscillator settings via MIDI CC with MIDI learn. In addition, you can control each oscillator’s rate and the overall depth via pitch wheel, mod wheel, velocity, aftertouch, and note values (key tracking) Cross modulation capabilities allow you to modulate one oscillator’s phase and frequency with the rate and depth of the other oscillator Turn either oscillator into a trigger pulse, which can be synchronized to subdivisions of the current tempo or the rate of the other oscillator Ability to save presets and wave tables Other settings include: Tempo override from external MIDI clock or via Ableton Link Ableton Link integration Pitch bender range control (maximum of 2 octaves) Background audio mode Oscillator pan controls: each oscillator can be panned to the left channel, right channel, or center Aftertouch sensitivity control (allows you to take it easy on those older keybeds) Bit depth resolution reduction controls for each oscillator, which opens up even more possibilities

Brand-new app. Brand-new powerful editor. We've listened for the past 10 years and we've re-written the application from the ground up - with speed, features and usability in mind. A GPU-powered, fast and advanced integrated editor is part of TouchOSC on all platforms - create the most complex of control layouts with ease and precision. MIDI, OSC and more... TouchOSC supports sending and receiving any number of MIDI and OSC messages on many connections simultaneously. On top of OSC over UDP & TCP, we support every type of wired & wireless MIDI connection your device can offer, including MIDI over USB. Cross-Network. Synchronized editing. Multiple instances of TouchOSC can be connected on the network for synchronized editing. Use the precision of your desktop's mouse and keyboard for fine-grained, detailed editing - test-drive and preview in real-time on all connected touch-screen devices at the same time. Scripting and local messages. A lightweight and fast scripting engine allows deep access to all aspects of your controller and enables limitless customization and interactivity. For less complex tasks we've added local messages - simply wire up controls to transmit or display values; no need to break out the big (code) guns. Easy. This is only the beginning... We've supported and updated TouchOSC Mk1 for more than 10 years and we're planning to do the same for this new version. We've already got a whole bunch of features cooking that were just not quite ready yet. There is so much more to come... Welcome to the next generation!

Verdict
The clearest difference is price: CV Mod at $1.99 against TouchOSC's $19.99. CV Mod also leads on review sentiment (80% vs 72%) and iOS requirement (11.0 vs 13.0). TouchOSC's advantage is rating (4.6 vs 4.0) and ratings volume (232 vs 8). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
CV Mod costs $1.99 and TouchOSC $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.
TouchOSC holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: TouchOSC has 232 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 80% of CV Mod's written reviews are positive against 72% of TouchOSC's, so the app with the better star average is not the one people write more warmly about.
CV Mod ships an update every 3 weeks, TouchOSC every 6 weeks. The most recent releases landed on September 24, 2026 and October 12, 2026 respectively.
