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 + * + ********************************************************************** + * + * Copyright (C) by Paul Barton-Davis 1998 + * + * Some portions of this file are taken from work that is + * copyright (C) by Hannu Savolainen 1993-1996 + * + * Although the relevant code here is all new, the handling of + * sample/alias/multi- samples is entirely based on a driver by Matt + * Martin and Rutger Nijlunsing which demonstrated how to get things + * to work correctly.
