-/* -*- linux-c -*-
- *
- * sound/wavfront.c
- *
- * A Linux driver for Turtle Beach WaveFront Series (Maui, Tropez, Tropez Plus)
- *
- * This driver supports the onboard wavetable synthesizer (an ICS2115),
- * including patch, sample and program loading and unloading, conversion
- * of GUS patches during loading, and full user-level access to all
- * WaveFront commands. It tries to provide semi-intelligent patch and
- * sample management as well.
- *
- * It also provides support for the ICS emulation of an MPU-401. Full
- * support for the ICS emulation's "virtual MIDI mode" is provided in
- * wf_midi.c.
- *
- * Support is also provided for the Tropez Plus' onboard FX processor,
- * a Yamaha YSS225. Currently, code exists to configure the YSS225,
- * and there is an interface allowing tweaking of any of its memory
- * addresses. However, I have been unable to decipher the logical
- * positioning of the configuration info for various effects, so for
- * now, you just get the YSS225 in the same state as Turtle Beach's
- * "SETUPSND.EXE" utility leaves it.
- *
- * The boards' DAC/ADC (a Crystal CS4232) is supported by cs4232.[co],
- * This chip also controls the configuration of the card: the wavefront
- * synth is logical unit 4.
- *
- *
- * Supported devices:
- *
- * /dev/dsp - using cs4232+ad1848 modules, OSS compatible
- * /dev/midiNN and /dev/midiNN+1 - using wf_midi code, OSS compatible
- * /dev/synth00 - raw synth interface
- *

- * Appreciation and thanks to Hannu Savolainen for his early work on the Maui
- * driver, and answering a few questions while this one was developed.
- *
- * Absolutely NO thanks to Turtle Beach/Voyetra and Yamaha for their
- * complete lack of help in developing this driver, and in particular
- * for their utter silence in response to questions about undocumented
- * aspects of configuring a WaveFront soundcard, particularly the

- is done purely at user level: there is no WFB parser in
- this driver, and so a complete reset (back to General MIDI,
- or theoretically some other configuration) is the
- responsibility of the user level library.
