Is the Music 4000 keyboard matrix documented anywhere? There's plenty of info at https://www.retro-kit.co.uk/page.cfm/content/Hybrid-Music-4000-Keyboard/, but no matrix. I've emulated the keyboard but would like to understand the matrix ...

... going only by end-user code, he created a brilliant code module for the Hybrid Music System. In that (unlike Elite adaptations), he's unique - to my knowledge.

It records via the qwerty keyboard easily and ... however charming leave me for wanting the sounds of music 5000. The Hybrid music junior software looked so cool and much more user friendly but ...

Have a look at Pi1MHz M5000. This does simplify the time slot method to significantly reduce process time.

Given we have original documentation like the schematic, and a RTL-level VHDL rendition, is it that important for the MAME implementation to illustrate the original pipeline as well? No, not that important. It's just that b-em did things when pc=0, 2, 5, 6, 7 which doesn't match the hardware, so wa...

Might be worth noting that it's an output-only device, which might relax the constraints a bit.

Can you also explain what happens in the other time slots initiated by /S0, /S1, /S4, /S6, /S7. It's a pretty complex pipelined design, and I don't recall exactly how the pipeline was laid out. So I'd need to go back to the VHDL and work this out again: https://github.com/hoglet67/Music5000/blob/ma...

Thanks to both, am trying to absorb the info which is not easy in this heat! Stepping back, what's happening here overall: - in time slot N*8+0 (/S0) the current 8-bit value of channel N is presented to the DAC by loading IC19/20 - in time slot N*8+6 (/S6) the input to the DAC is cleared, by clearin...

At the risk of jumping in and muddying the waters: the 6070 has two modes, nominally ADC and DAC, which in the Music 5000 are both used as output modes (because the ADC mode is meant to be used as a successive approximation approach and therefore also operates as a DAC.) So the ...

Thanks. I understand all of this from the documentation and the b-em implementation, but what I don't understand is how the hardware uses those four control bits of the stereo position to affect what is fed to the Am6070 to result in the 7 positions. What does IC24 actually do to achieve this? IC24...

I can try to help you out with this tomorrow, if no one else beats me to it. Each channel has a stereo position which controls for how many time slots the channel is sent to the left channel vs the right channel (I think there are 6 time slots in total). The counter you mention controls when the sw...

Nigel, I can try to help you out with this tomorrow, if no one else beats me to it.

The counter you mention controls when ...

Hmm, was expecting at least some help with understanding this. Got notified of a reply that had been removed before I read it. So how is the 3 bit stereo position actually being applied? It's fed to the counter IC24, but what is this actually doing in terms of feeding the Am6070? The other emulator ...

I've been implementing the Hybrid Music System range of 500, 5000, 3000 into MAME, and used the b-em implementation as a reference. With a ...

Some other wild ideas:

Add more members of the family? like the Hybrid Music 2000

Network? viewtopic.php?f=3&t=16565

Video Digitiser? a Pi can have a camera

mouse ?

USB harddisk ?

We can also add at least some of the Music 87 software, i.e. as supplied by Peartree with their rebadged Music 500/5000, which was written in BCPL. Then, of course, AMPLE as supplied by Hybrid with the Music 500 / Music 5000 is a Forth-based language with only the core implemented ...

Hi I just spotted the advert for Hybrid Music Junior! Oh wow does that bring back some excitement. I remember seeeing that advert when it came ...

The original keystrip for the Hybrid Music System is rather primitive so I have recreated it in the Acorn keystrip style, which I find more attractive and easier to read.

Dear All, Just checking if anyone has recently refurbed a Music 500 with very similar symptoms to those experienced on Retro-Kit: https://www.retro-kit.co.uk/user/custom/stardot/hybrid5000-borked-early.mp3 vs https://www.retro-kit.co.uk/user/custom/Acorn/3rdParty/Hybrid/audio/InConcert-PilgrimBeart.mp3 ...
