Bias BNT-6 Night Training - 6 Channel Analogue Drum Synth & Trigger Pads

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"Very cool 6 channel Japanese analogue drum synth - controls for Volume, Attack (Snappy for snare) and Pitch (Decay on hats), Input Sensitivity. Capable of some pretty decent drum sounds - especially if you drive it with another drum machine and turn up the Sensitivity - overloads the signal and the source sound can bleed through adding extra dirt and colour."

"This has a lot in common with the Drumfire brain, and Simmons SDS series. It can get very low bass like a Roland TR-808

Sequence the sounds from the trigger inputs with a Beatstep Pro, or other trigger/gate sequencer from a modular synth.

This is an extremely rare unit!"

RARE VINTAGE JSH DX-5 PRO-RHYTHM MINI SYNTH

YouTube Uploaded by ThePromoHouse on Jul 12, 2011

via this auction

Also known as the Coron DS8, Asama Drum Sync, Storm Drum Sync, Grant PS-7 Percussion Synth, KMD Drum Exciter, Cortez D-2 Mini Synth, BIAS BS-2, and possibly more. See the Coron label below. Anyone know why there were so many branding for this? I think this holds the record.

via the listing: "The Mini Synth, when connected to my headphones, covered a massive range of synthesised sounds and this is an incredibly flexible unit for its mini size and I would, I guess, sound fabulous in the right hands and with the right input and amplification (I haven't got the means to really put it through its paces). Please feel free to ask as many questions as you wish - I am not familiar with synthesisers (I obtained this in a job-lot including vintage microphones and headphones)"
