Synthesis Technology E440 Discrete OTA VCF
You have probably heard of the SSM2040 filter chip, used in the Prophet-5 Rev 2, Voyetra 8, and others. Although short-lived, the SSM2040 filter had a unique sound different from a Moog, ARP, or other 4-pole lowpass filters. Why? The design used a clever discrete OTA gain cell that responds beautifully as additional gain is added to the input signal.
The E440 provides three simultaneous filter slopes: 2 Pole (12dB), 3 Pole (18dB), and 4 Pole (24dB) for selective timbral shaping. Voltage control of filter resonance (rarely found on other filters) is also available.
The E440 is based on the 5U MOTM-440 filter with additional features such as separate outputs for each filter slope and an input Drive control.You have probably heard of the...
