Folks,

Is there an online article or something in the manuals (can't find) that explains some of the waveform naming conventions?

There are several name suffices on Waveforms that recur, such as in

0983 French Horn Solo Of
0982 French Horn Solo-
0981 French Horn Solo+

What does "Of" and "-", "+" mean?

In the Wv category there are several names that I'm curious about?

1366 P5 Sawdown 0 dg I understand "Sawdown" and "0 dg", but what's "P5"? Maybe Prophet 5?
1368 P5 SawDown PhaseRndm. Presumably "PhaseRndm" refers to the initial phase. But how can it be random if it's a waveform stored in memory. Can the waverforms be read out at random initial points?
1373 OB Saw --- Presumably Oberheim? How are they different from P5 Saw?
1375 1o1 Saw. What's "1o1"?
1379 Mg Ramp. "Moog Ramp"? This doesn't sound like a sawtooth, but like a combination of two waveforms, maybe a square and a saw an octave higher
1374 Saw --- higher harmonics aren't strong enough for a sawtooth, any ideas?

Then there are some kind of pulses presumably

1380,81,82 --- P10-1, P10-2, P10-3
1383,84 --- P25-1, P25-2
1385,86 --- P50-1, P50-2 --- These sound like square waves, so maybe the others have shorter duty cycle 25% and 10%?

Thanks!
Todd

What does "Of" and "-", "+" mean?
”Of” is short for Offset. A Waveform with an Offset is usually one where in the original sample there was a distinct attack characteristic. A French Horn has a characteristic brass “blat” attack, the Offset Waveform would be the French Horn Sample set provided without that attack portion. Literally, it is the French Horn Waveform sans any attack. This is used in the engines ability to transition active Elements during play.

Part of the XA CONTROL (Expanded Articulation Control) feature, is a function that takes place on Mono sounds that is better suited to create a legato transition between Elements. Rather than every time triggering the Waveform with the recorded attack, if a new note is triggered before the release of the previous note (true legato), an Element set to XA CONTROL = Legato will replace the initially attacked Element. This new Offset Waveform will begin to sound; it will be used as long as you continue a legato gesture and because it does not have a recorded attack the transition to the new pitch occurs as if played on a single breath.

A reattacked Element would sound very much like the Horn player had just taken a breath before attacking the new note. The fact that ‘mono’ and XA CONTROL ‘Legato’ are in play, you can create French Horn phrasing that includes breathing, attacking and more legato behavior. You can ‘attack’ the first note, and play legato, without taking a new breath (attacking a new note).

You will find many Solo instrument set for this Legato behavior... usually they will either have “legato” in the name or “AF1” or “AF2” in the name, as these are Switches usually tasked with activating the mono mode necessary to activate the Legato behavior.

A “-“ (minus) or “+” (plus) next to a name has to do with matching the phase of the audio contained in the sample set. This can be useful when building ensembles—typically you’d want to be able vary the phase of additional components to get a more realistic ensemble feel, with resorting to detune or a more prominent delay. (If Waveforms are exactly the same within a sound you’re building, the illusion of an ‘ensemble’ is more difficult to create).

Your guesses are pretty spot on about Prophet V is “P5”, “Ob” is, indeed, Oberheim... the difference in the sawtooth waves with those tags is the source instrument. “1o1” was a plastic/fantastic Roland Analog synth from back in the day. Each brand of analog synth had a unique quality in sound, and character in their filters.

Pulse Waves are listed with a P, followed by the duty cycle, so P50 is a square (equal time Off/On 50%)

It might be interesting to post an interview with some of the MONTAGE/MODX programmers, and have them translate all of the abbreviations contained in the ROM Waveform List... because it’s not just what they mean, it’s about how they can be used.

I'd be interested in an interview with the programmers and how to use the waveforms.
