Soundtoys EchoBoy - Manual (Page 37)

First, the initial echo will ALWAYS appear in the left “Ping” channel with the initial repeat
determined by the echo time set for Ping, be it in milliseconds or Notes. The second echo will
always appear in the right “Pong” channel and “when” it appears it is based on the Ping time
PLUS the Pong time. Even if the Pong delay time is set SHORTER than Ping, you will always
hear Ping FIRST and then Pong.
As you turn up the Feedback control things can get really interesting as each successive repeat
is predicated on the other side being heard. For example, say Ping is 500 ms and Pong is 250
ms. If you play a note you will hear Ping 500 ms later, Pong 750 ms later (Ping + Pong) and
Ping again at 1250 ms (Ping+Pong+Ping) then Pong again at 1500 ms (Ping + Pong + Ping +
Pong) and so on and so on. So the delay repeats are relative to each other with each repeat of
Ping showing up in the left channel and each Pong repeat showing up in the right channel but
only AFTER the other has been heard.
Things can get even wilder and truly strange depending on when either Ping or Pong is set to a
specific Note value with Midi sync and the Pong is set to Time in milliseconds or any
combination thereof. Setting both Ping and Pong to Note values and syncing to Midi clock can
provide for some fantastically rhythmic synced delays.
Again keep in mind that Ping Pong is always stereo out, but that the input is always summed to
Mono. This is true regardless of whether you are running on a mono or stereo insert.
Ping-Pong Echo Tweak
Pressing the Tweak button while in Ping-Pong Mode launches the Tweak menu showing the
associated tweak parameters for Ping-Pong mode. You’ll notice that there only two parameters,
Width and Balance. The Width knob works as previously described for the Single Echo mode, so
the only thing new here is the Balance control.
