Hattons have their own brand 8 pin decoders at £10.00 - Hattons Model Railways Ltd DCR-8pin-01 Max continuous load (amps):1.1A Peak amps: 1.6A Number of functions: 4 Function load (amps): 0.2 Back EMF: Yes Sides: 2 NMRA Compliant: Yes Quiet drive: Yes Auto detect (DCC): Yes Qty of speed steps: 128 2 or 4 digit addressing: Both Heatshrink: Yes CV#31 contains the most significant bits of the two-byte address and may have any value between 00010000 ($10) and 11111111 ($FF) inclusive.CV2 Vlow, Start Voltage (useful range 0-100) CV3 Acceleration rate (each unit = 7mS between speed steps) 255 max.

(139=sound 1, 140 = sound 2, etc).CV1 Short decoder address 1-127 valid. So far as CV's that control individual sound volume, according to this list CV 139 through CV 155 control the sounds associated with F numbers.
