Pwm Lfo Setting Fun; Pre-Mix Levels; A Possible Cause For Clicks - And A Solution; Changing The Voice Rotation - Alesis Andromeda A6 Tips And Tricks Manual

Two sources of phase cancellation are:
1. Using too much PWM on square waveforms, especially non-square waves which can
sweep out of the range where anything generates if you are not careful. Time your
sweeps so that the sound doesn' t drop out so bad.
2. Too much detune. In which case, simply adjust the detune upwards to a more
appropriate values.

2.18 pwm lfo setting fun:

Some things to think about from Michael Caloroso
The A6 LFOs can be bipolar, you can also configure them as positive- or negative-going unipolar
waveforms, or you can throw in an offset and make either peak higher than the other. And if that
isn't enough fun, you can change the LFO waveshape; IE you can continually change the triangle
from a falling ramp through triangle to a rising ramp. Works with the square wave too. And the
waveshape can be modulated in real time :)
David Evans describes some other synthesizer hints for emulating PWM settings:
Yamaha CS50: Slider goes from 50% to about 90-95%. Dedicated PWM LFO is bipolar (so yes, if
you set the slider at maximum you only get PWM for half of the LFO cycle). The maximum LFO
amplitude seems to be +/- 100%, meaning that with the base slider set at 95% the LFO can still
drive the pulse width to almost zero.
Oberheim Xpander: Bipolar about 50% as the default (this can be change, of course).
Roland Alpha Juno-2: Slider goes from 50% to about 95%. PWM LFO is a little weird: since the
base PW control is the same as the PWM depth control the LFO always goes from 50% to the depth
you have set on the PW slider. Unipolar above 50%, then. Also the LFO is global for all six voices.

2.19 pre-mix levels:

Any synthesizer in which you can set pre-mix levels and post-mix levels is bound to have
some interesting effects over fixed level synthesizers. In general, keep the levels to a sum of
50 or under for best sound. For more tips, see the " Creating Wet Sounds" tip list for even
warming up the synth further!
2.20 a possible cause for clicks – and a solution
From Ronald:
Try this: choose a simple sound with a fast attack. Turn tuning off. Now play sixteen very high notes.
Now play some very low notes. Alternatively, make the sound monophonic, and play alternating
high and low notes.
What is happening here is that you set all VCOs playing at a high pitch. The notes have ended, but
the VCOs are still running - only the VCAs have been closed. When you play the opposite notes, the
VCA opens before the VCO has reached the new key pitch. If the VCO was running at a pitch which
is close to the new note, you won't notice it so much. But if the pitch of the new note is far away from
the VCO's previous pitch, you hear it. Autotuning makes it show up more by setting the pitch far
away from the range in which you are playing.
I'm not near my A6 right now, but I seem to remember that the quirk goes away if you set the
optimizer to fast response.
