The '''Dynacord ADD-One''' (advanced digital drums) is a German-manufactured, American-designed [{{Cite journal|url=http://www.muzines.co.uk/articles/dynacord-add-one/968|title=Dynacord ADD-one (MT Nov 1986)|journal=Music Technology|date=November 1986|issue=Nov 1986|pages=24|last1=Wiffen|first1=Paul}}] [drum machine](/source/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](/source/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 [{{Cite web|url=http://www.musicgeardaily.com/dynacord-add-one-rare-drum-machine/|archive-url=https://web.archive.org/web/20090213162854/http://www.musicgeardaily.com/dynacord-add-one-rare-drum-machine/|url-status=dead|archive-date=February 13, 2009|title=Dynacord ADD-one rare drum machine {{!}} Music Gear Daily|website=www.musicgeardaily.com|access-date=2018-06-05}}] for up to 20 seconds. Actually it is 8 bits with 4 bits of companding according to one of the designers Michael Doidic.[{{Cite web |url=http://www.musicgeardaily.com/dynacord-add-one-rare-drum-machine/ |title=Dynacord ADD-one rare drum machine |access-date=2018-06-05 |archive-date=2018-01-01 |archive-url=https://web.archive.org/web/20180101154447/http://www.musicgeardaily.com/dynacord-add-one-rare-drum-machine/ |url-status=dead }}] 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](/source/LCD).

==Sounds==
Bass drums, congas, snares, Hihats as well as single-cycle waveforms (sine/triangle etc.) contained on EPROMS.[{{Cite news|url=https://www.dreamsong.de/vintage-drums-dynacord-add-one|title=Vintage Drums: Dynacord ADD-One|date=2011-02-27|work=Kreativ Musik machen|access-date=2018-06-05|language=de-DE}}] 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](/source/MIDI) which allows it to be controlled from an external device such as a [synthesizer](/source/synthesizer) or [electronic drums](/source/electronic_drums).
