Main Features |
- The interface works in one direction only – it only receives MIDI data. Instrument’s keyboard, knobs, sliders and switches are not transmitted as a MIDI data.
- MIDI Thru function (no MIDI Thru-box is necessary).
- Controls the YAMAHA’s keyboard (CV for VCOs) from MIDI. The instrument’s tone parameters (control elements on panel) are not MIDI controllable.
- The instrument’s keyboard (VCOs) is controlled only manually or only by MIDI Notes – not both ways simultaneously.
- Easy user control of the interface parameters via MIDI CCs (as well as SysEx for experts):
» 49 MIDI Notes (4 octaves) range
» Transpose function (over whole range of MIDI Notes)
» Embedded arpeggiator (Up, Down and two Up-Down modes, all modes syncable by MIDI or internal clock)
» User defineable size of received MIDI Notes buffer (useful for arpeggiator)
» Hold pedal – CC #64 (works with MIDI Notes buffer)
» Local On/Off function – CC #122 (turns the interface on/off)
» User defineable optical indication of the interface status
» User selectable MIDI Channel for communication - 128 internal memory presets to store the interface user settings (the instrument’s tone parameters cannot be stored).
- Original features of the instrument are not changed and the instrument can be used the same way as before the interface installation.
- Very easy installation without the instrument circuits modification.
The interface recognizes MIDI commands:
- Note On/Off
- Program Change
- Standard CCs (Hold, ASO, ANO, RAC, Local Off/On)
- Own CCs (# 16, 19-23, 119)
- Common MIDI Synchronization – MIDI Clock
- Common System Reset
- System Exclusive Messages
Installation |
Installation of all MIDI interface parts into the instrument is very easy and no problem should occur if all instructions indicated in the installation manual are kept. Please note that a complete beginner should not carry out the installation. At least basic manual dexterity and knowledge of soldering are required.
Note that there are differences in the installation process for Yamaha SY-1 instrument! The SY-1 is electrically the same but mechanic construction is little different from SY-2. So you have to adapt the montage of MIDI sockets and LED / Reset button and also placement of the interface board. Wiring of the interface to instrument’s keyboard circuit and to SM-1 board remain the same for both SY1 and SY-2 instruments.
It is recommended to adjust the Yamaha instrument according to instructions in service manual of the instrument before the interface installation. This ensures trouble-free adaptation and usage of the interface.
The SY2-KBD MIDI kit package contains all necessary parts (board, cables, coupling elements, etc.) incl. owner’s and installation manuals in printed form.
