Arps/Harmonicon/DTuneOfDoom on your PCM80/81 (must read!)

This is for the tweaker.
Others should just suck a sweet and play the blues..

Say you have a PCM80 w/the Pitch FX card or an 81, which has pitch shifting algorithms on board already.
And maybe you have a looper or delay w/hold function... or an E-Bow or a synth
Put it thru what I'm about to describe, playing/looping a single note.

Let's create an Arpeggiator using any pitch shifting algorithm. We only need ONE voice for this.
You need to patch the pitch value of a voice to the LFO and use the 8 pivot points in the patch; check the user manual to get familiar with this powerful feature in you PCM if you haven't used it yet.
For simplicity sake we're just arpeggiating a major scale, so patch the pitch (I like that!) in this way:
0 = + 0 cents
16= +200 cents
32= +400 cents
48= +500 cents
64= +700 cents
80= +900 cents
96= +1100 cents
112=+1200 cents


The patch Src will be the LFO and the Dst will be your V1 Pitch.
Use the LFO with different waveforms and see which you like better... check the square wave!
Experiment with the pitch GLIDE for the smoothest transition between steps...
Hold on a note and listen for the scale going up and restarting...
Experiment with different steps from the ones I used, to get a more even range (duration of the notes) and, obviously, more interesting intervals than a scale

What if start using more than one voice pitch shift? Patching it to the same LFO and maybe with different intervals? How about some counterpoint.... contrary motion, bass pedal + lead moving up or down, bass moving up or down + lead pedal, parallel motion, similar motion, oblique motion...
Try patching the 2 voices pitch to different pivots so that they don't change at the same time but interact one thru the other... instant Bach art of fugue!


Let's get to harmony!
We need 3 or 4 voices... definitely the QUAD>HALL algorithm...
Same trick... patch each voice up to 8 pivots to the LFO and think musically about the 3 or 4 intervals you want to hear as a chord. It can be a monster 4 voice (actually 5 if you include the dry note you play) chords generator, great for music and for practicing work.

Tap the tempo if you want the LFO to be in sync....

Nice uh?

But boring... the LFO is gimmick... we can do better than that.

Back to the first example, a 1 voice pitch generator- This time we are going to use a MIDI CC with values 0/1/2/3/4/5/6/7 or 1/2/3/4/5/6/7/8 depending on how your MIDI controller counts the MIDI hex range (0>127 or 1 >128). A MIDI slider is cool or a pedalboard allowing each switch to send the same MIDI CC with a different value.
If you patch an interval to every pivot point (up to 8 in a patch) you will be able to recall any note in any order (w/different switches) or in a linear range (slider).
Do the same for 2, 3 or 4 voices... creating up to 4 patches with 8 pivot points each. You can use a single MIDI CC to remote ALL voices at the same time... OR you can use 2 or 3 or 4 MIDI CCs, one for each voice pitch and mix and blend their pitches in total harmony glory.

I believe you could also create a step thru switch, using a simple footswitch connected to the rear panel plug of the PCM... there should be some patches showing how to create this kind of switch to step thru pivots.

Add beautiful verb, always available on this mighty machine.
Let these simple techniques inspire you on how pitch shifting can be used for musical ideas... maybe let this inspire you in creating your next song.

Do you want the ultimate detuner?
Guess what?
use the QUAD>HALL and patch the 32 pivots (4 voice x 8 pivots each) to different cents, up and down... think micropitch, within +/-12 cents.
Patch the voices to the LFO or to the different waveforms singularly to add more randomness to the changes... or even to your playing dynamics and adjust GLIDE for best transitions :wink: ... AND LISTEN to IT!


What else could you do?

Brilliant Tutorial Professor Italo!
Any PCM -80/81 User w/Pitch FX Card should now thinking!
Great Post,
Great knowledge
