Jumping directly to edit pages
You can jump to the detailed edit pages for any of the blocks
shown on the Patch Panel. To do this:
1. Select a jack on the block that you want to edit.
You can select any input or output on the block.
2. Press the Jump button in the Parameter Details area,
at the top right of the display.
This will take you directly to the page of the selected jack’s
block. For instance, if you’ve selected one of the inputs or
outputs of VPM Oscillator 2, pressing
Jump will take you to
the VPM Osc 2 page.
Muting oscillators
The PCM Oscillator and each VPM Oscillator can be muted
temporarily, so that you can hear their effect on the sound.
To do this, select any of the block’s input or output jacks,
and edit the check-box in the parameter details area. You can
also use Tone Adjust buttons 1–6 (VPM Osc 1–6) and 9
(PCM), which are assigned to these parameters by default.
Filter B and 4-pole routing
When the filter Routing is set to 4–pole , only Filter A is
active. Filter B no longer passes any audio from input to
output, and both input and output jacks are grayed out.
Any cables previously connected to Filter B will remain in
place, with their color changed to black & red to indicate the
filter’s disabled status.
4–1a: Algorithm Select
Algorithm [List]
Algorithms do three things:
• They create a set of default connections between the
elements on the Patch Panel, which can then be altered as
you wish using patch cables.
• As part of these connections, they set the Link
parameters for Mixers 1, 2, and 3, as well as the Filter’s
4-pole/Parallel parameter.
• They specify which VPM Oscillators are carriers, and
which are modulators. This affects the way that the
Macro parameters work. You can edit these settings after
selecting an Algorithm, if desired, to account for changes
due to user-created patch cables or oscillator settings.
Algorithm groups
The algorithms are divided into several groups, selected by
tabs on the left-hand side of the Algorithm Select popup.
VPM includes the most useful configurations of VPM
Oscillators, routed through either 4-pole or parallel filters.
The PCM and Noise algorithms, below, are primarily based
on this set of configurations.
The first entry, Blank Patch , is a special algorithm with only
the simplest of connections: VPM Oscillator 1 goes straight
into the Output Mixer. Use this if you want to build your
own algorithm from the ground up.
PCM + VPM offers a selection of VPM configurations
layered with PCM samples.
PCM->Filter->VPM includes the standard set of
configurations, using PCM (through a 2-pole filter) as an FM
modulator.
PCM->VPM -> 4-pole are similar, but these route the
unfiltered PCM directly into the VPM Oscillators, and then
processes the result through a 4-pole filter.
Noise->VPM -> 4-pole use the Noise Generator as an FM
Modulator.
Many of the PCM and Noise algorithms have two
variations, labeled I and II . In the I versions, the PCM or
Noise goes to the input of a Modulator; in the II versions, the
PCM or Noise is routed to the second Carrier input, in
parallel with the VPM Modulator.
Processing are special algorithms for simple waveshaping,
ring modulation, and/or FM modulation with PCM or live
audio input.
Vintage DX features all of the original DX7 algorithms,
without any filtering. Feedback is much more flexible on the
MOD-7 than it was on the DX7, and so when the original
algorithms differed only by feedback routing, they’ve been
grouped into a single selection. To disable an external
feedback routing, just go to the input jack that the feedback
leads to, and set its
Level to 0 .
Remember, you can use patch cables to change any of these
algorithms to suit your needs.
Which algorithm should I use?
Algorithms are just shortcuts for configuring the Patch
Panel. You don’t have to use them at all; if you prefer, you
can just make all of your connections using patch cables.
The preset algorithms do make it easy to call up commonly-
used setups, however.
In general, with more carriers, there’s more potential for
layering; with fewer carriers, there’s more potential for
complex and detailed FM modulation.
The “all carriers” algorithms (10, 20, 30, 40, 50, and DX
#32) are good for creating thick layers, or for simple additive
synthesis (up to 7 partials, plus noise, each with its own EG).
The Processing algorithms are a good place to start if you
want to transform a PCM sample into something new, or
process a live audio input.
The PCM + VPM algorithms are good for layering samples
with VPM.
