CHAPTER 19:Sound Waveform Generator
S6J3200 Series Hardware Manual Document Number: 002-04852 Rev. *G
463
Notes:
−
Control of WGCHEN under 4.1 causes ALL 0 to be output at the point that SWFG operation is
enabled, but this is not included in idle time. It should be noted that start idle time indicates the
period from the start of sound source generation in accordance with control by WGCHSTART
under 4.2, up to generation of ALL 0.
−
Refer also to 3.1.
3.1.2.
Waveform
The waveform is the fundamental wave that makes up the sound source.
One of 3 waveforms (sine wave, sawtooth wave, square wave) is selectable by software. For details,
see 4.7.
3.1.3.
Frequency
Frequency is a sound source component that corresponds to the pitch of the sound.
One of 64 frequencies is selectable by software. For details, see 4.7.
3.1.4.
Run Time
Run time is the time to generate a sound source of the specified frequency.
One of 31 run times from 1 ms to 4 seconds is selectable by software. For details, see 4.7.
Notes:
−
Neither the start nor end idle times are included in the run time.
−
Fade in time and fade out time are both included in the run time.
3.1.5.
Fade In Time (ATTACK)
Fade in time is time required for volume change from -96 dB to 0 dB immediately following run time
start. Fade in time is included in run time.
One of 24 fade in times from 1 ms to 1 seconds is selectable by software. For details, see 4.9.
3.1.6.
Fade Out Time (RELEASE)
Fade out time is time required for volume change from 0 dB to -96 dB immediately following run time
end. Fade out time is included in the run time.
One of 24 fade out times from 1 ms to 1 second is selectable by software. For details, see 4.9.
Notes:
−
Fade in time and fade out time are both included in the run time. Configuration of settings that
result in fade in time, fade out time, and the total of these times being shorter than the run time is
prohibited.
−
If the total of these times exceeds the run time, fade in will start from -96 dB and a switch will be
made to fade out before 0 dB is reached.
−
Each configuration should be under condition below.
Attack ≤ FSLEN, Release ≤ FSLEN and Release ≤ FSLEN
