■The dd14 is a portable drum pad all made out of good Japanese plastic ! With very typical design, it features 8 pads with adjustable sensitivity, numeric display and internal stereo speakers (i f you want to know: 3W RMS 8 Ohm). Also a special "scraper pad" for a kind of ribbon scratching effects, quite similar on the sampler Yamaha SU-10.
■Basically it's a rompler with 24 ROM sets + 5 RAM users. Each set memorize which sound is assigned to 1 of the 75 available sounds,mainly percussive sounds but also musical ones like marimba. No, It is NOT possible to add sound nor modify them, you can maybe circuit bent it for your nerdy pleasure.
■The Yamaha Arranger contains 100 ROM styles to play with, with auto bass function , variation and fill-ins.
It can be synched to external Midi clock. Special Chord Memory has 2 entry modes:
▫ Real-time quantized record where each pad and combination acts as a key/chord variation (Maj, Min, 7th, Min 7th, Major 7th, 7sus4, m7-5, dim)
▫ Step record mode where you can enter a chord, specify how long it will last, then go on to the next one
