Controls: Gen Dlg >> Stream >> Wave >> Play >> Interp
Macro: PlayMode

This control is similar to the one at the bottom of the Arb dialog. Normally, you will want to leave it in Interpolate mode. This means that Daqarta will interpolate between Play file values to find the proper output value at any given instant of time, just as the normal internal Wave types do.

But if you are using the Play file for something other than a sound source, there may be times when you want only the exact file values, such as when using the file as a test sequence generator. Round mode will always select the nearest exact value.

Step mode is often more useful for sequence generation, since it uses the Timing dialog instead of the Rate control. The Step Timing option, for instance, allows you to step through the Play file using exact data values, but holding each for a specified number of samples.

You can also use the tricks discussed for the Arb file to select random values from the set of Play data.

In Step mode, Trigger Gen Sync defaults to the Timing Step size, even if Spec or Slow are active. If you set Timing Step to the Play size (shown on the message line when you select a Play Wave), then the sync point will be the start of the Play cycle.

Macro Notes:

Use L.1.PlayMode=Interp, L.1.PlayMode=Round, or L.1.PlayMode=Step to set the Left Stream 1 Play Data mode.

Note that setting the Play Data mode directly via macro does not automatically set the Wave to Play. Use Wave=Play to do that.
