MFM2

MFM2 is an effects plugin that begs to be fed with Midi control signals. Especially notes that are played on a Midi keyboard (or recorded in a sequencer) can make a big difference as to what MFM2 can do! You can for instance use the KeyFollow modulator to tune its filters, or to tune its delay lines. Also, notes trigger the lfos and envelopes, so Midi helps you keeping modulations in sync and on the point.

Some audio applications can unfortunately not send Midi to effects plugins. Fortunately there is a way to easily circumvent this flaw: The Keyboard Control. It’s in the second tab on the bottom and lets you click whatever note you want. You can automate the clicks in you audio application, which creates 2 automation tracks: One is for the Key and one is for the Gate/Velocity. Make sure the automation of Key is always on top of (or immediately before) the Gate. This way you can get most of the benefits of Midi in MFM2 even though you audio application might not yet be up to this highly useful concept.

Effect vs instrument mode (Logic etc.)

Some host applications such as Logic can’t send Midi to effects but offer workarounds themselves – they allow you to use effects like instruments instead. It is important to understand how your host handles FXs that can be controlled by Midi messages.

Logic Pro

You have to first open MFM2 as an instrument as shown above.

Then you have to choose a side chain input, in this case Bus 1. Any audio going to bus 1 will also be sent to MFM2.

Now you can assign a track to the MFM2 instrument and use the keyboard Midi messages to “play” the delay.
