audiowerkstatte midi-restarter & midi-clock-divider

"The midi-restarter helps you to start or stop your MIDI-slave independent of your MIDI-master, but alway in perfect synchronisation.

You push the buttom and the audiowerkstatt midi-restarter sends a MIDI-start/stop-message at the beginning of the next bar to ensure that all following MIDI-devices run in the correct timing.

There are 3 modes of operation:
1. At the beginning of the next bar, a MIDI-stop-message and immediately after that a MIDI-start-message is sent. In this mode, a standing sequencer is restarted and a running sequencer is "pushed" into the correct timing. This mode does not work with all MIDI-devices as some devices require a short break between MIDI-stop- and MIDI-start-message. For these devices, the second mode can be selected.

2. A short time before the next bar starts (one MIDI-clock-message=1/24 quarter-note), a MIDI-stop-message is sent and then at the next bar a MIDI-start-message is sent. In this mode, a standing sequencer is restarted and a running sequencer is - after a very short break - "pushed" to the correct timing. This mode corresponds to the first and is intended for MIDI-devices that require a short break between MIDI-start- and MIDI-stop-message.

3. If the sequencer is running, a MIDI-stop-message is sent at the next bar and if the sequencer is standing, a MIDI-start-message is sent at the next bar. In this mode, a standing sequencer is restarted and running sequencer is stopped at the next bar.

It can be switched between the time-signatures 4/4 and 3/4.

You can also set whether only the newly created MIDI-clock and the MMC commands (start, stop, continue) are sent or the midi-data, received at the MIDI-in, will be mixed with that."

"The audiowerkstatt midi-clock-divider is a clock-divider for the MIDI-clock.

The audiowerkstatt midi-clock-divider divides the MIDI-clock of the MIDI-master, whereby the MIDI-slave runs correspondingly slower. The division-ratios are 1/1, 1/2, 1/3, ..., 1/8, 1/9.

If the division-factor 1/1 is selected, the MIDI-clock is simply passed through. With the division-factor of 1/2 the MIDI-slave runs at half the speed. So 16ths-notes will be 8th-notes and the loop is twice as long.

Very useful to double the loop length of the MIDI-slave (eg MIDI-sequencer or [audio-]looper). When using the division-factor 1/8 and an originally one bar long loop runs over 8 bars.

And good for experimental musicians, especially if an odd division-factor is selected and MIDI-master and slave seem to be not in sync, but from time to time come together in perfect sync.

You can also set whether only the newly created MIDI-clock and mmc commands (start, stop, continue) are sent or the, at the MIDI-in incoming data, will be mixed with that."
