CMS is an authority on ARP synthesizers. They are the premier US service centre, restorers and upgraders of classic ARP synthesizers. Earlier in the year they released the 1047E multimode filter Eurorack module based upon the filter in the ARP 2500. And they’ve promised to do a lot more than that with their CMS Eurorack project. And now we have the 1004T Pearlman Oscillator just around the corner.
CMS 1004T Pearlman Oscillator / T-Mixer
Through a short video on YouTube we get our first glimpse of the waveforms, the prototype module and the sound of the oscillator. It’s an exact reproduction of the unique and revolutionary temperature controlled ARP 2500 VCO circuit combined with the “T” waveform mixer, both designed by Alan R. Pearlman (hence the name). It can generate 5 waveforms in both positive and negative form: sine, triangle, square, saw and pulse. The magic of the wavemixer is that you can blend them together to produce some very distinct sounds. Pulse width modulation and FM is also included.
The video is pretty simple, just an oscilloscope and some low-quality audio but it gives us a glimpse of what’s coming and that’s pretty exciting.
Other modules to come include the 1032 Dual Analog Envelope, the 1055 VC Balanced Modulator / Mixer / Panner, the 1066 ARP 24dB Ladder Filter, the 1067 Dynamic Voltage Controlled Amplifier and the 1070 Low Noise Precision Audio Mixer. Combined with the 1004T Oscillator and the already released 1047 E Filter and you have the basic ingredients of the massive ARP 2500 synthesizer in Eurorack format.
