No known emulator supports the Music Machine. There was a club advertised through the magazine Sinclare User which sent out a computer tape twice a year full of interesting software developed for the Ram Music Machine. This was contributed to by the members and included thing such as a 128k sampler, fsk syncing mods to the original software and many useful midi tools to name but a few.<br>
The Music Machine was never used for producing sound effects in [[:Category:Demos|Demos]]. Now, thanks to Jose Leandro, the hardware specialist of the spectrum, with his famous page : http://trastero.speccy.org/cosas/JL/JL.htm We can know more about this hardware.
== Technical Specifications ==
Information from the manual:
The Music Machine incoporates two Ferranti devices for digital-to-analogue (DAC) and analogue-todto-digital (A to DADC) conversion. The part numbers are ZN429E8 and ZN449 respectively. The circuit also include a Motorola [[6850 ACIA chip]] (Asynchronous Communications Interface Adapter) for handling the [[MIDI]] channel, two anti-alias filters (one for input and one for output), a discrete microphone amplifier and a headphone amplifier. The clock signal for the ACIA and the ZN449 is provided by a ceramic oscillator.
The incoming signal from the microphone amplifier is sampled to an 8-bit resolution at a rate of 19.444 thousand samples per second. This yields an analogue bandwidth of approximately 9.5KHz 5kHz which is in fact the cutoff frequency of the filters.
The clock signal for the ACIA is '''unknown'''. As said above it is based one the same oscillator as used for the ZN449, however, the oscillator is probably ''whatever'' MHz (?) divided by ''whatever'' (?), and its unknown if the ACIA and ZN449 clocks are using the same divider (ie. the ZN449 samples at 19.444kHz, but the ACIA may, or may not, use another frequency).
