MIDI — STOP THE LOT

What Does It Do?

This device filters out selected MIDI messages from the MIDI data stream.

Handy if you don't want spurious Clock and Active Sensing messages, for example, starting, stopping, or slowing down a piece of gear. Maybe you need to stop program change messages, or pitch bend.

It has 1 input and 2 outputs: one filtered, and one just an unfiltered copy of the incoming MIDI (effectively a MIDI thru).

Plug in a MIDI cable — say, one carrying clock — and the device sends out two copies, but one will have the clock messages filtered.

Simply press the button to cycle through the filters. The selection is recalled on power up. Incoming MIDI data — note, hex, and message type — is displayed on the OLED screen.

"I needed something to solve a problem with my Akai MPX16 and MPX8. The Akai's would drop notes or be very laggy over MIDI, which is a big problem when you are sequencing drum samples! Anyway the Mindburner Stop The Clock has stripped out the clock and active sensing data that the Akai MPXs can't use anyway. This means the MIDI interface of the Akai's isn't overloaded and they now work perfectly."
