The DK700 is a polyphonic synthesizer with voice assignment. It actually contains 6 complete and individual synth modules (termed voices or channels). It is fully programmable and able to store up to 73 programs in its memory when in DK700 mode and 55 patches for the simultaneous control of slaves when in master keyboard mode. Each voice contains two digitally controlled oscillators (to ensure the best pitch reliability on the whole extension of the wall tempered scale) with analog waveforms. It also comprises a 24 dB/octave low pass Voltage-controlled filter and an envelope generator; this means that the DK700 has 12 oscillators, 6 filters, 6 envelope generators and 4 low frequency oscillators providing parallel modulations of parameters such as pitches, square waves P.W., filters. All this is controlled by specific controls and memorized in the heart of the DK700; the "Programming Unit", which also provides to the management of the 73 timbric programs and 55 patches.
The DK700 is basically an updated version of the Siel Opera 6 with added midi-functions. It's quite rare and could be regarded as one of the best Siel ever built. Unlike the DK70/80, the DK700 has six filters and three LFOs to shape your sounds. Once you edited the sound you had in mind, there are plenty of memory patches to store it. This synth has a fat tone even without using a Chorus-unit. The sounds are very versatile and analogue. From synth-horns to weird effects, the Siel does it all with ease.
