Good but could be better

A very good leslie sim but the iOS version doesn't have any factory presets. There is an option to reinstall them but nothing happens. Its not a big problem but it does mean that you just have one default preset and the rest is up to you. Took me about an hour to understand with all the parameters and then started saving some presets. This is a great alternative to the Ventilator for a fraction of the price. Offers far more tweaks than a vent too. My Nord Electro 6 leslie sim is OK but this takes it to the next level.

Its an AUv3 plugin but it does work standalone. However, it doesnt show up as MIDI device so I have to use Midiflow and then a StreamByter scriot so I can map leslie speed to Electro half moon switch.

Bottom line - very good but standalone mode could be improved.

Response from developer

These are PLUGINS, you need to use them as AUv3 plugins and make your connections inside a AUv3 plugin host of your choice (AUM, Camelot, Cubasis, etc.).

GSI ROTARY SPEAKER

This rotary speaker really improves the sound of the VB3M. I would highly recommend this app.
