Here you can see how to make your own cable for the Cassette Interface on the PPG Wave 2, PPG Wave 2.2, PPG Wave 2.3 and PPG EVU.

1- Ground
2- From Cassette
3- To Cassette

4- Not Used
5- Not Used

Diagram shown as if looking at the PPG back panel.

The Cassette Interface allows you to upload and download banks of sounds from and to a cassette recorder or a computer (I would recommend using a computer these days).

I have used this information to make a cable with which I can send banks from my computer to my PPG synthesizers.

Thanks to John Trevethan for providing this information.

Here you can see how to make your own cable for the Rhythm Interface on the PPG Wave 2, PPG Wave 2.2, PPG Wave 2.3 and PPG EVU.

1- Start/stop
2- Ground
3- Internal Clock Output
4- Not Used
5- External Clock Input

Diagram shown as if looking at the PPG back panel.

The following lists show various applications of syncronization with the Rhythm port and DIP swith blocks. (see below)

External device as a slave, PPG as master clock:

  1. Connect pin 3 to the external device's clock input.
  2. Connect pin 1 to the start/stop footswitch input on the external device if there is one.
  3. Set the clock rate on the PPG using the switch blocks (see below) to whatever rate the external device needs.

External device as master, PPG as slave:

  1. Connect pin 5 to the external device's clock output. (Pin 5 needs to see a 1-volt rising-edge pulse.)
  2. Set the clock rate of the PPG to the appropriate value, depending on what the external device is sending.

To record a sync-to-tape tone from the PPG:

  1. Connect the clock out (pin 3) to an input on your recording console.
  2. Set the input level on the board to +2VU.
  3. Set the PPG DIP switches as follows: 8-switch block- 1 & 3 down, 4-switch block- 1 & 2 down.
    This will produce a 192PPQ tone.
  4. Record the tone to tape.
  5. Enter a 1 next to RUN in the sequencer display to run the sequencer at the desired tempo.
  6. Stop the tape when finished.

To sync the PPG from above tone:

  1. Connect the device the sync-tone is recorded on to a console which can raise the output signal to +5VU.
  2. Connect this boosted signal to the clock in (pin 5) on the PPG.
  3. Set the PPG DIP switches as follows: 4-switch block- 1 & 4 down, 8-switch block- when syncing from tape, the pulses sent from the 8-switch block can be used to drive other devices that are connected to the PPG's clock output.
    To do this either switch 1 or 2 (but not both) should be down. The other switch (and only one other can be down) used will depend on how many pulses per quater note the external device needs to see at it's clock input.
  4. Enter a 1 next to RUN in the sequencer display and start the playback of the sync-tone.
    To get the most accurate results, make sure to start the sequencer from the beginning of the sync-tone.
