Amazing!!!!

This thing is everything!!! Paired up with all my other apps, this modulator just breathes life and movement into my programming. Extremely flexible and amazing mod options!!!!!!

MIDI-only version, not “little brother”

This is the MIDI FX version of MMM, which shows up as an audio FX as it has an input follower, you want both versions and they should be packaged in the same download together rather than create this confusion. I thought “little brother” meant this was a simplified version but instead it’s complimentary.

Thank you! We tried to offer it as a bundle but unfortunately this is only possible for paid apps or apps offering in-app purchases…

NextGen Modulators

This probably deserves the best app of 2023 award. It works seamlessly and intuitively. The level of control and possibilities are astonishing. It‘s 100% reliable and it‘s free. This is by far the best modulation system on iOS and is on a desktop a great addition even to bitwig.

Thank you so much for such praise. Nothing beats the feeling of knowing our stuff is helping people create! 🥰

Incredibly useful

This app has a lot of potential uses, particularly given the range of modulation and envelope following features. It can transform your workflow as you are able to centralize a lot of the parameter tweaking all in one place.

My only suggestion would be for it to be possible to choose to “hide” knobs or sliders that are not being utilized to cut down on the visual clutter. The number of options can be overwhelming at times when used with specific apps rather than full-on devices, and it would be simpler to only have what I need, (perhaps have each block have an individual on/off accessed through the same menu where the cc info is set). Having additional templates with either just the top or bottom sections available would also be useful.

Overall it has a lot of features and allows me to use one app versus the string of apps I had been using before to acquire similar levels of control.
