Page 3: Introduction
It has a distinctive sound and was clearly designed to stand alone as a 'synthesizer on a chip'. If you don't know or care for the history of the C64 or SID, then MIDISID is a MIDI-based 6- oscillator synthesizer with a choice of 4 waveforms (plus combinations) per voice, ADSR envelope per voice, one ﬁlter with resonance control per chip, modulations such as PWM, ﬁlter sweeps,...

• a barrel jack which will take a 9v centre-negative power supply. See Powering MIDISID • a standard MIDI 5-pin DIN for midi in. Currently MIDISID only accepts MIDI via the good old- fashioned 5-pin DIN. If your keyboard or other device uses midi over bluetooth or USB then use a suitable adaptor.

Page 6: Stereo Output
Stereo output The two-SID version of MIDISID has a stereo output jack, which can give the illusion of stereo but there's no mixing or panning. The 3 voices from one SID go to one channel and the 3 from the other go to the other channel.
Page 7: The Three Modes
USB MIDI interface or an audio interface that has traditional MIDI sockets. MIDISID should render a midi ﬁle as well as possible within the limitations of the SID. In practice some ﬁles will work better than others. Files that only use fewer channels and fewer notes at a time per channel are more likely to sound best.
Page 8: Polyphonic Mode
Using any of the modes, you can use a DAW to send MIDI to MIDISID and then capture the resulting audio. Logic Pro calls this an "External MIDI Instrument", Ableton an "External Instrument...
Page 9: Midi Control Change Messages (Cc)
MIDI Control change messages (CC) MIDISID currently responds to: • pitch bend messages (0xE0-0xEF) (full range of control is one tone either way) • program change messages (0xC0-0xCF) • mod wheel messages (0xB0-0xBF (CC) 01) Using the menu (Monophonic or Polyphonic >...
Page 10: Voice Mapping
Voice mapping General MIDI mode Each MIDI channel is assigned to voice. So on a 2-SID MIDISID, channels 1-6 are mapped to voices 1-6. One special case - if a note is detected on channel 10 (traditionally percussion). Then channel 10 is assigned to voice 6, with channels 1-5 mapped to voices 1-5.
Page 11: Playing A .Mid File And Getting The Most Out Of It
Playing a .mid ﬁle and geBng the most out of it In General MIDI mode the MIDISID ﬁrmware will do its best to render a .mid ﬁle, but there are a few things to be aware of. The ﬁrst is the natural limitation of the 2-SID MIDISID which has 6 voices. This means that only MIDI channels 1-6 will be played.
Page 12: Preset Instruments
For some types of music, polyphonic mode may work well with a .mid ﬁle. It removes the limitation of channels 7-15 being ignored and will use the next available voice for each note, but it will use the same sound patch for all notes. Preset instruments Note that sometimes the voices are designed to be used in a particular register.
Page 13: Muting Voice 3
This is a feature of the SID chip which is useful if you're using voice 3 as a LFO or envelope for one of the other parameters (these are currently outside the scope of MIDISID) and it's also useful if you're using ring modulation, or just wish to build sounds using two voices rather than three.

• Other modern replacements may work but are untested and unsupported. • Real SIDs are unsupported. If you wish to try them in MIDISID it is at your own risk. There are no guarantees for the safety of your SID chip, which may be at breaking point even if working, or for the safety of your MIDISID.
Page 15: Updating The Firmware
When updates are available, it's easy to update the ﬁrmware. With MIDISID powered off, use a USBA->micro USB cable to connect the Pico to a computer, using the Pico's micro USB connector. Give a double-tap on the reset button. (Clip the button into place if it was supplied separately.) This should put the pico into boot mode.
Page 16: Troubleshooting
Troubleshoo)ng Noisy audio out If you're using a battery, check the voltage of the 9v battery or try a new battery. If a power supply, make sure it's 9v. Check that with a meter if you can, or try a different power supply. Make sure that you don't have anything plugged into the micro USB port.

Page 18: Bring Your Own Box
Appendix B Bring your own box MIDISID will work ﬁne in its supplied form. However, it is designed to be easy to ﬁt into a case or enclosure if you choose. It can be split into two parts. The main (bottom) board can be mounted in the bottom of a case. The two parts are connected by a standard 4-way jst-sh cable.

Page 28: Version Control
Version 2.1 :   This version and the Version 3.2 main board are required to run ARMSID. This combination is known as 'MIDISID Neo' Fixes pitch bend, may have been broken since adding support for pitch bend range. In affected versions, pitch bend could still be used if a RPN 0 (sensitivity) is sent with a suitable value.
Page 29: Planned Features
Adds information about new features - saving / loading, portamento(glide) speed Adds information about save/load, modwheel support. Updates menu map. Updates the manual with information about MIDISID 'Neo' (board rev 3.2 and ﬁrmware 2.1+) which now supports ARMSID as well as SwinSID Adds the table for the functionality of the four encoders / context.
Page 30 The following features are ﬁrmware enhancements and so will be available to you as and when they're done. This is a record of intention, not promises. If there's anything here that you're very keen to have, or if you have suggestions, please get in touch. support for sustain pedal (CC/64/v) (switch, sustain mode on/off) (we have upvotes for this, it'll be done soon)
