MINDBURNER MIDI - MIDI clock source and metronome
MIDI MASTER CLOCK
An accurate, rock-stable MIDI master clock generator for synths and modules. One input, four independent outputs — no need for a separate MIDI THRU box to drive multiple devices. Timing tight enough to make a DAW's software clock look laughable.
Built-in MIDI metronome with an audible click, switchable off when not needed.
Power
- Pretty much any 2.1mm 9–12V DC supply, 1A+ capacity, tip positive
- The type sold on eBay for LED strip lights works well
- Runs nicely off a PP3 9V battery in a 9V-to-2.1mm case — handy for a quick jam (DC power recommended for long sessions)
- Option available with UK 240V 3-pin to 12V DC power supply
Modes — Internal / External
A switch on the left of the unit sets the mode.
Controls
| Encoder Knob | Sets the tempo. Press to send MIDI start/stop messages, effectively starting and stopping the clock. |
| Reset / BPM | Restarts at the last BPM setting used before power was removed. To set a tempo, e.g. 130 BPM, dial it in then remove power — it comes back at 130 next time. |
| LED Display | Shows tempo in BPM. The rightmost segment flashes to the beat. Another segment flashes when clock start/stop is being output. |
| Tap Tempo (TT) | Tap out a beat and the device will attempt to lock to the tapped tempo. |
| Remote Jack | 3.5mm jack for remote start/stop — wire up a remote switch, or use a footswitch with a 3.5mm to 6.35mm adapter. |
Features
- Clock LED indicates background clock or MIDI IN activity
- Audible metronome click, switchable
- MIDI IN passed thru to all 4 outputs in both modes
- Clock always running in Internal mode, start/stop via encoder button
- Outputs pass "MIDI power" to power self-powered devices
- Easy-to-read white LED display
- BPM range 10–350
- Designed and built in Northern Ireland
Expansion
My MIDI-to-DINSYNC module adds CV clock options to this stable source — great for driving a TR-606 and TB-303 in perfect timing. For MIDI clock division, see my MIDI Clock Divider, also listed.
Syncing to DAWs
Most DAWs are designed to sync to MTC (MIDI Time Code) rather than MIDI clock — these are not the same thing. This device, like most hardware clocks, outputs MIDI clock, so DAW sync isn't generally possible, though it may depend on the specific DAW.
