Get to know them!

The RJM Music Mastermind LT MIDI foot controller packs all of the impressive MIDI capabilities and configuration options as its big brother, the Mastermind GT. Its compact size and lighter weight makes it a great fit for your effects pedalboard, providing you comprehensive control over your MIDI-capable pedals. And it's a great controller for music software too, with a USB port for direct connection to your Mac or PC. To change presets and parameters on numerous MIDI devices at once, it doesn't get much more efficient than the RJM Music Mastermind LT MIDI foot controller.

Compact size fits on your pedalboard

If you have MIDI-capable effects pedals on your pedalboard, the Mastermind LT is the perfect way to control them. It's very compact and can be powered by standard pedalboard power supplies. Up to 16 devices can be controlled simultaneously.

Comprehensive MIDI control and programmability

Whether you're controlling effects pedals or interfacing with music software, the Mastermind LT offers comprehensive MIDI control for its size. In all, you can create up to 768 preset configurations, each with 16 pages of buttons and support for up to 16 connected devices. You can send a program change message to all 16 devices with a single tap of a Preset button, and up to 10 other MIDI messages (CC, PC, Note, and Sysex). Mastermind LT also lets you create Instant Access buttons, which can send up to 20 messages simultaneously — you could re-program your entire pedal and amplifier rig with a single footswitch.

Interface with your Mac or PC

Connect the Mastermind LT to your Mac or PC via USB to program it using the Mastermind Editor software, or to send MIDI commands to software like your DAW or amplifier modeling apps. There's also a port for a USB thumb drive, allowing you to install custom presets without connecting to a computer.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
