What's New in 7XDXFM 4OP FM Loop Maker

2.1

May 30, 2025

Updated UI Removed Randomise as this was not very helpful. Improved mutate so it replaces the old of randomisation. Start off with a tone , copy it as backup, then press mutate a few times. Then paste and try again. Better results this way.

💚💚💚💚

love all these yet its really missing randomizers for instruments and etc parameter randomize would complete these apps!

Excellent app, why have I not heard of it before?

Bought all 5 of your apps in the package. Like what I see so far, simple to use, great results. Nice work. Some sort of parameter lock in this app and step probability in all apps would be the icing on the cake.

Non legible small font unnecessarily

On an iPhone the fonts are stupid small for no reason. It amazes me! It’s like they don’t even look at their own product. Why do you make it so hard to read?! Fair sound that can be very strange but with an old fashion late 1980s UI. Weird animal.

Response from developer

Apologies. Hopefully the update has helped.

Ambitious mess

Disclaimer: I’m on an iPad Pro, and I own this developer’s other apps, so I knew the UI can be a little challenging, but this one is more of a struggle.
* Main issue is the sound engine tends to lag behind the user input and control, leading to a frustrating play experience. A groovebox that’s hard to groove with.
* Feature request: Add ways to randomize the sound setting, ratios, and patterns will lead to more happy accidents and faster workflow.
* There only seems to be four selectable algorithms unless I’m missing something, which is little disappointing.
* The sample looper seems out of place and difficult to use.
Maybe with some updates, performance improvement, and polish this could be fun.

Response from developer

Hi thanks for feedback. Could you email any feature requests as I don’t always see all comments on reviews. I’m already looking at a nice new extra feature right now. Always good to hear of feature requests though and will look at those. Ps there are 5 algorithms. The fifth one allows each operator to be a carrier (4 separate audible oscillators) while two of these still get to modulated themselves . This is common to be included in most FM synthesisers
