Retrieve options for rendering ProTracker modules. See also
pt2_render().
Value
Returns a named list of options that can be used for rendering
ProTracker modules (see pt2_render() and play()).
It contains the following elements:
sample_rate: an integer value specifying the sample rate of the output in Hz.stereo_separation: an integer percentage determining how much the tracker channels will be separated to the left and right stereo output channels.amiga_filter: acharacterstring specifying the hardware filter to be emulated. Can be"A500"for emulating Amiga 500 hardware filters, or"A1200"for emulating Amiga 1200 hardware filters.speed: An integer value specifying the initial speed of the module measured in 'ticks' per row. Should be in range of1and31.tempo: An integer value specifying the initial tempo of the module. When speed is set to6, it measures the tempo as beats per minute. Should be in the range of32and255led_filter: Alogicalvalue specifying the state of the hardware LED filter to be emultated.timing_mode: on the original Commodore Amiga timing in tracker modules could be handled using different approaches. The first is the 'vertical blanking' method, were timing was based on each time the monitor blanks (before being redrawn). This method thus depends on the monitor that was used. PAL monitors operated at approximately 50 Hz, wereas NTCS monitors used 60 Hz. Alternatively, the Complex Interface Adapter (CIA) offer hardware-level timing and was system independent. You can set the timing mode by specifying"cia"(default) here, or"vblank"(currently, only PAL is supported).
