*help is implemented for the supported *commands as well as BASIC's SOUND
and ENVELOPE commands.

i.e. *HELP ENVELOPE gives:

RDSP's BASIC ENVELOPE command:
Syntax  ENVELOPE N,W,FQ,O,T,S13,S2,D1,D2,D3,A,D,S,R
N = envelope number (128 selects sample 1 etc).
W=Wave or Sample ID.
F=Filter nybble
Q=Filter Q
O=modulation options:-
&01-&04 ADSR: (&01=pitch, &02=filter,&04=PWM),
&08-&40 3 stage envelope:
(&08=amp, &10=pitch, &20=filter, &40=PWM), &80 = loop 3 stage envelope
T=3-stage step-time in 1/100ths of a second
S2=Steps in stage 2
S13=Steps in stage 1&3
D1-D3=Delta for stages 1-3
ADSR envelope

To load RDSP type:
*RMLoad System:Modules.Audio.SoundChip.RDSP

Then to start RDSP type:
*Rstart

The RVolume command may be used to lower or raise the master volume. Maximum volume is 255:
*Rvolume <number>

To stop RDSP
*rstop

n.b. Typing *Rstart again will increment the reference count to RDSP and will require a matching *rstop
