Alpha Editor is an editor and patch library app for the Roland Alpha Juno synthesiser family. It provides direct access to all of the Alpha Juno’s patch parameters through a clear and reactive touch based interface.

Alpha Editor is a MIDI based app; it uses MIDI to communicate with your Alpha Juno. In order to do so, it requires a coreMIDI compatible adaptor or a connection to a Mac or PC that provides MIDI capabilities.

Alpha Editor is compatible with the Roland Alpha Juno 1 & 2, MKS-50 and HS-80. It is intended to only be used in conjunction with one of these synthesisers: it does not double as a generic MIDI controller and it does not produce any sound by itself.

What’s New

Version 1.4

Fixed a crash caused by MIDI clock messages being received by the app.

This issue was causing the app to crash in pretty random times, but generally when editing a parameter; hopefully it is squashed for good!!

Fantastic Editor

Lovely interface design. This app really multiplies the value of my Alpha Juno 2. Thanks!!! Bug report: the patch names are not transferring properly to the hardware. Feature request: it would be awesome if I could -export a bank- so that I can load it into the hardware after editing.

Forget the jog wheel!

Editing my review.

Initially gave 1 star because I was only able to control note on/off and pitch. I have switched midi interfaces and the app is now working 100%.

Only thing this app needs IMO is the ability to midi control the app so users can control the parameters of these wonderful synths via sequencing. That would make this a five star app.

Never written an app review. Best app I've ever purchased

Barre none the best thing I've ever gotten for 6 bucks.

Love everything about it.
