MIDI Pro 4+

I paid for the full version of this app because I want to support this developer.

I tried using this app primary to help generate backing parts to practice soloing and accompanying with my primary instruments. The user interface is very simplistic but that doesn’t bother me as much as there’s little guidance to figure out how to use the thing. Pros: - lots of flexibility - many built in progressions - sound fonts library can be exchanged Cons: - synthesized melody and parts are way too busy to be used as backing and often interfere with each other harmonically; I end up muting half of the tracks - acoustic guitar backing parts could strum rhythms - track levels cannot be muted or level adjusted during playback - the animated character is cute but wasted ui space.

Update: Ended up not using this app, deleting it; Chordbot ends being more practical for my needs and at a much lower price tag. Hope you put my $15 to good use!

We appreciate the feedback. Working on new release and better guidance on the product page. The product support page into were you can ask questions is on the App Store. In the future we will provide that contact information inside the app so that a contact method is easier to find. Regards

Every time I load up a soundfont, it keeps on giving me this error: “Player soundbank preload failed”. I’m thinking it’s because the app seems to be dated.
EDIT: The error code is 10871.

What is the error code reported next to preload failed?
Fixing a similar issue in the upcoming release. ( would need error code to see if it the same)
Work around: keep the original default font FluidR3_GM.sf2 font an.d then add the new font. Do not delete the default one
if you are up to it resetting to default values will reload it. Otherwise it is available on the web.
