Dynacord Add-One
Electronic musical instrument From Wikipedia, the free encyclopedia
The Dynacord ADD-One (advanced digital drums) is a German-manufactured, American-designed [3] drum machine that was first released in 1986. It uses recorded samples to produce its sounds through analog voltage-controlled envelopes and analog filters with resonance, to self-oscillation per voice. It comes with 1 Mbyte of memory and can be upgraded up to 8 Mbytes.

Sample rate and bit rate
The unit can sample up to 50 kHz at 12-bits [4] for up to 20 seconds. Actually it is 8 bits with 4 bits of companding according to one of the designers Michael Doidic.[5] The sample rate and therefore the pitch is variable, like the Fairlight and E-mu EII and other earlier samples, via the 8 separate DACs - variable pitch via sample clock rate change. Later digital samplers, including those that operate in software utilise interpolation and other techniques to alter the pitch of a sample - the effect, particularly in the low-end is not the same.
Display
The unit features an 80-character backlit LCD.

Sounds
Bass drums, congas, snares, Hihats as well as single-cycle waveforms (sine/triangle etc.) contained on EPROMS.[6] With the optional 'Add-One Drive' one can sample any recorded sounds into the sampler via the microphone/line input with on-board compressor.
External control
The Chain mode allows these to be called up in any order and stepped through by a footswitch. The unit also features MIDI which allows it to be controlled from an external device such as a synthesizer or electronic drums.
