Layer Balance Knob

Sets the balance between Layer A and B after the individual layer level controls. The centre position has both layers at their selected levels, turning left decreases the overall volume of Layer B and visa versa.

Master Volume Knob

Sets the master volume of the instrument.

Master Tone Knob

Adjusts the overall tone of M-Tron Pro IV. Turning the knob left progressively turns down the high frequencies.

Master Pitch Knob

Speeds up or slows down tape playback to increase or decrease the overall pitch of the instrument.

Brake Button

With original Mellotron and Chamberlin models, adventurous players would apply pressure to the flywheel slowing the tapes down to create effects ranging from subtle pitch fluctuations to extreme tape stops. We’ve seen several instruments with a hole cut in the lid to allow players easy access to the flywheel but thankfully, in the virtual instrument world, we don’t need to resort to such butchery!

When activated this button assigns the Brake effect to your mod wheel (CC1). This will supersede any CC1 assignment elsewhere in the instrument.

Rewind Button

This implements a two-second rewind time for each key after it’s played and released. When activated, if the key is replayed during its rewind time, it will start at the appropriate point in the tape rewind, not from the start.

CC Button

Click this button to open the CC view where you can assign and edit your MIDI CC controls. More here: MIDI CCs
