MIDI Clock Control of Tap Tempo Delay

If you are using a Program that uses either Tap Tempo Delay effects (Tap Tempo Mono Delay and/or Tap Tempo Ping Pong), you can control the delay time of the effect(s) via MIDI clock. This makes it possible to synchronize the delay time to the precise tempo of an external MIDI sequencer or drum machine.

To synchronize delay time to MIDI clock:

➀Connect the sequencer or drum machineÕs MIDI OUT to the Q20Õs [MIDI IN]. This provides a one-way connection, since this is all we need to control the Q20Õs delay time via MIDI clock (we donÕt require the Q20 to send MIDI information back to the sequencer or drum machine).

➁Select a Program that uses either the Tap Tempo Mono Delay effect or the Tap Tempo Ping Pong effect, or both.

➂Set your sequencer or drum machine to output MIDI clock.

Usually, MIDI clock will be output from your sequencer or drum machine only when it is in play; when not playing, no MIDI clock information is sent.

➃Play some audio through the Q20 to hear the effect.

Note: If the MIDI clockÕs tempo changes, the Q20 will chase it. If the MIDI clock signal is discontinued, the delay time will remain set to the last tempo which the MIDI clock had been.

DELAY: 500.0mS [120.0BPM] 1/4

The delayÕs Beat Count parameter (found to the right of the Delay Time parameter) is used to determine what note value the effect should synchronize to. Example: If you set the Beat value to Ò1/4Ó, then you can synchronize to the quarter-note beats of the incoming MIDI clock. If instead you set the Beat value to Ò1/8TÓ, you can synchronize to eighth-note triplets relative to the incoming MIDI clock signal. You can also set the Beat value to a dotted-note variation, such as Ò1/8.Ó, which lets you synchronize to the dotted-eighth-note beats relative to the incoming MIDI clock signal.
