HT3670C

The HT3670C is a CMOS VLSI designed specifically for Electronic Drum sound applications. With a comprehensive range of 18 instruments and 36 rhythm/fill-in effects, the device provides an exceptional amount of sound flexibility for a multitude of drum sound applications. Other important sound functions are provided in the way of adjustable tempo and volume keys in addition to replay and demo key functions. With the ability to control an external keypad and with full control over the internal sound processing circuits, Holteks embedded fully functional 8-bit microcontroller provides the programmable ability to create many varied and multi functional applications. Sound output is provided by HT3670C through a four-channel ETS (Electronic Tone Synthesizer) in addition to two-channel sound processing circuit.
