TECH main core is a Motorola 68000 CPU manages 32 voices polyphony, EMU DACS are 6 X 16 bits AD1860 (from analog devices company).
a basic patch VINTAGE KEYS is composed by 1 or 2 PCM waveforms Primary + Secondary (rompler technology) with some edit controls, including:
sample start offset
- tuning pitch
WAVETABLE internal 8 MB ROM contains 249 PCM at 16 bits 39 KHz sampling rate mostly based on vintage synthesizers e.g Rhodes, Wurlitzer, Hammond, Prophet, Minimoog D, ARP Odyssey, Mellotron, Oberheim but also some acoustic shots and drum samples.
UPGRADE the PLUS OPTION is a non-standard SIMM (model: 9055) can be installed into the dedicated slot doubling the ROM samples to extra 8 MB (means + 185 new samples).
Latest Vintage Keys modules (number 9056) were directly released as PLUS standard with a specific logo script.
PLUS EXTRA SOUND LIST Dyno Rhodes, Yamaha DX7 FM Electric Pianos, Emulator II, Emulator III, Sequential Circuits, Oberheim, Roland analog synths, ARP analog synths, Emu SP-1200, Boss DR55, Roland TR808, Chapman Stick, Fender P-Bass and Electric Sitar.
PERFORMANCE the 32 voices polyphony can be assigned to up to 16 parts with some control parameters:
individual Midi channel
- pitch tune
ENVELOPE 3 EGs:
- EG1 primary amplitude: 5-segments AHDSR
EG2 secondary amplitude : 5-segments AHDSR
EG3 AHDSR is assignable by control matrix to various parameters such as filter or pitch.
TIP: AHDSR stands for attack, hold, decay, sustain and release.
LFO 2 delayed digital modulators:
- LFO 1: osc pitch
- LFO 2: VCA.
Both LFO have some structure inluding 5 waveforms with variable symmetry (triangle, sine, square, sawtooth and random) and key retrig function.
FILTER structure is based on 3 ASIC chips: the primary and secondary OSC features an individual digital resonant filter lowpass at 2 / 4 poles configuration.
EFFECTS none, except the CHORUS parameter but it is a voice trick channels, halving polyphony.
MAINTENANCE 2 common issues:
- DISPLAY: is not uncommon to split dead black zones on the display.
ENCODER: after some times the encoder may go berserk just clean it with Q-tip and dedicated liquid product.
- RAM: 256 patches
- ROM: 256 presets.
Battery replacemen: RAM works with a 3V lithium battery model Br-2340 set in a plastic holder, but I managed to fit a more common BR-2325.
RELATED FAMILY there is a LOT of confusion between "vintage" models:
- Classic keys: budget version with cheaper board, some effects but no filter (means no cool sweep pads). The weakest.
- vintage pro: many years later the vintage keys has been updated with "PRO" with brand new 32 mb wavetable and Z-plane filters . Far better!
- Vintage Keys: Keys version of Vintage PRO, 32mb ROM.
VST PLUGIN / SAMPLED VERSION the vintage keys has many classic instruments, many have a VST free plugin versions:
