TOPOGRAF

View Product Page

TOPOGRAF is a drum sequencer with three tracks, that works with a "topographic" principle; it contains a number of drum patterns arranged in a "virtual map"; and with two knobs MAP X and MAP Y you can set a position in this map. With one knob per channel the density is defined; and a CHAOS knob brings some randomness into the whole process. All in all a few knobs for a lot of drum patterns you probably wouldn't make this way by yourself - a nice source of inspiration and alo great for playing live.

TOPOGRAF is the AE modular version of the Grids module by Mutable Instruments. It is 100% identical to Grids. The user manual for that module can be found here. https://mutable-instruments.net/modules/grids/manual/

Module power consumption: 20 mA

Advanced Settings and Modes

The Topograf has the exact same program as MI Grids and the manual for Grids (see above) can be used. However here is a detailed explanation of the different advanced settings and modes.

Changing the clock resolution

You can change the clock resolution on the Topograf like this:

  • unplug all CV and hold the TAP (RESET) button for a second to put the Topograph into advanced settings mode
  • the FILL1 knob changes the clock resolution which you can as a pattern on the 3 LEDs
  • 4ppqn = first LED is on
  • 8ppqn = second LED is on
  • 24ppqn = third LED is on
  • Turn the FILL1 knob to select the resolution you want
  • Hold the TAP (RESET) button again for a second to save the settings

You can experiment with 4 or 8 ppqn, but 24 ppqn is usually only useful if you wan to clock the TOPOGRAPH directly from the MIDI bus.

The following video explains the advanced configuration options. https://youtu.be/GLRYptx4Zmg

Patch Suggestions

Gaetan from the forum suggests:

Example for a bass line

  • Trigger the envelope generator of your voice with the topograph's kick
  • Patch the same kick trigger to your SEQ16 clock
  • Patch the SEQ16 to control the pitch of your bass line

Now, every time topograph sends a kick, your sequence will advance one step.

More fun

  • AND together the kick and snare, and use them to trigger your voice's EG
  • Use the hihat to clock the SEQ16

You're going to have some pretty groovy bass lines with that

Or for a melody

  • Clock your SEQ16 with a regular clock, and send the output to a Sample & Hold
  • AND the HH and the kick, and use it to trigger both your voice's EG and the S&H
  • Use the output of the S&H as you voice's pitch

You'll have a stable melody that will skip steps according to the state of the Topograf
