1. Moog Theremini Extra Waveforms


I learned from Dani (xtheremin8) on the Theremin World Forum that there are extra waveforms on the Theremini that can be accessed by using Midi CC#90. I used Midi-Ox to check all of the 127 values for the CC#90 used for waveform selection. I found these values gave working waveforms:

1-9, 13-18, 21,26, 27, 43, 51, 60, 73, 74, 86-89, 93-97, 101, 103, 108, 109, 112 & 124-127.

In order to determine duplicates, I used the software Audacity to record the waveforms for the above values, with the wave table scan rate, scan amount and scan position controls all set to 0. The waveforms are as shown below. The numbers in parenthesis are the CC#90 values.

1. Sine (0):

2. Triangle (1):

3. Super Saw (2):

4. Animoog 1 (3):

5. Bright (4):

6. Hollow (5):

7. Etherwave (6):

The following are by CC#90 values in parenthesis:




















(88) too weak:

















Comparing the waveforms above and using my ear, besides the Theremini's standard seven waveforms, there are 12 unique other Waveforms. Those 12 waveforms are listed below as values for the CC#90 command:

7, 8, 9, 13, 14, 17, 18, 86, 87, 89, 93 & 101

2. Listen to 12 Extra Waveforms:

I made a new library "ThereminRCA14Waves.theremini" that has Thomas Grillo's original RCA Theremin preset, followed by the waveform "Etherwave" used instead of "Animoog 1", followed by the extra 12 waveforms that are named by the values of the CC#90 command. If you switch between the 14 presets, you can hear the effect of changing the waveforms only for his preset. You can download the "ThereminRCA14Waves.theremini" library by right clicking HERE and saving the file.


3. "Space Scapes" Theremini Library file of 32 Presets:

I use the Theremini mostly for creating soundtracks for my Astro Imaging Youtube videos along with other synthesizers. An example can be seen and heard (best in HD) HERE.

I created a "Space Scapes" Theremini Library file of 32 presets using only the extra 12 wavetable waveforms hidden inside the Theremini and you can download it by right clicking HERE and saving the file. Your Theremini will need the Theremini Firmware Update Version 1.1.0 or later version installed to access the extra waveforms. The waveform names for all of the presets will appear blank in the Theremini Software Editor and on the iPad an incorrrect name will appear. If you have trouble downloading the file on an iPad, if you have the DropBox app installed, you can download the file by clicking HERE. I made a soundtrack using the Space Scapes library file with the scale set to Mixolydian and you can hear it HERE:


4. Theremini Editor Using "Virtual MIDI Sliders":

I put together a Theremini editor using only Midi Continuous Controller numbers (CC#) using the free windows software "Virtual Midi Sliders". That software will allow you to access the other extra waveforms in the Theremini. It is an old program (2005) created by Wouter van Beek, but works very well on my newer 64-bit Windows 7 notebook. You can download the software here:

You will also need to download my VMS file, named "ThereminiCCSlider.vms" by right clicking HERE and saving the file.

When you run the Virtual Midi Sliders software, you will need to open that VMS file. Before you can use the software there is one change that you need to make in the settings of your Theremini. In SETUP, go to MIDI CV SETUP and change the CC# of 20 to 19 for the PITCH value of MIDI CC OUT. That is because Moog also uses CC# 20 for changing the waveform "Scan Amount" of the Theremini.

In the menu, select MIDI/Set Up MIDI Devices and select "Moog Theremini" for the input and output MIDI devices.

Here are some notes to get you started:

Dragging any of the sliders will change the settings for that parameter for the Theremini. Try the Volume Slider first. Please note that for the Theremini, there are two pages of controller sliders as shown above. For operations of the program that require you to select any slider(s), you need to right click the number at the top of the slider to select that slider and the number will turn blue. For some sliders, I set up minimum and maximum values, shown as blue lines in the slider, but the slider will still operate all the way to the maximum value of 127, so be careful. Once you make adjustments you can write the preset to the Theremini, by changing the value of the last slider "Save Preset" and save the Slider Settings under FILE in the menu. You can also use the snapshot feature to save the values of all sliders and buttons. The program allows 4 banks with room for 10 controller snapshots each to be saved and loaded. Note that I disabled the sliders used for Low Note and High Note, because they were giving erratic results.

Please note that this is not software that is authorized by Moog in any way and use at your own risk.

A listing of the Continuous Controller Numbers (CC#) and their Theremini functions and values are shown below:

5. Beginner Theremini Youtube Video:

I put together a YouTube video that covers the Theremini Firmware Update version 1.1 that Moog released in December 2014. The video also includes a demo of Moog's Advanced Software Editor for the Theremini. It may be useful for others starting out like me with the Theremini being their first Theremin or for others considering purchase of a Theremini. A direct link to the YouTube video is HERE.
