 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

For decades now, I've only ever played quality instruments. Here at work, somebody dumped a real cheapie acoustic on me because they'd given-up trying to learn to play. It's a "MartinSmith", £58 brand new  It was horrible and impossible to play. My buddy just happened to have a truss-rod wrench and so for giggles, we turned the screw until the string-height was more reasonable. Whoa, what? Total transformation and we were both gob-smacked. Checked the intonation (open-string vs 12th fret which is an octave) and it was as good as any guitar can be. Now I'm loving this thing  I wanted to install a pickup but not the internal piezo type because, IMO, they sound horrible. Went on AE and found a sound-hole type for £1.53 After tax + shipping, it was £5. It arrived on Saturday and it certainly looks/feels like a good quality product.So now I want to incorporate a backing-track (MP3), inside the guitar body, with it's own stereo jack socket. I want it to be PicoMite controlled so that I have other programmable possibilities. I have read, here about add-on sound-module options and now I'm overwhelmed/confused so what will be the ultimate config for this? |

Forgot to ask: When playing a track in MMBasic, do we have access to the time-line or do we just fudge it? Thinking about the possibility of triggering events at certain trip-points during playback. |

I was confused. Buy a Martin&Co guitar for 58gbp ?  But then I read "MartinSmith". Ok .. different brand.... Volhout PicomiteVGA PETSCII ROBOTS |

@Volhout 150K for a lump of wood with strings on it???? I'm definitely in the wrong business I see a lot of £2,000 Martins at open-mic gigs and owners who can barely play. They all have the aforementioned piezo pickups and sound thin and tinny but they seem to believe that they spent the money and therefore they must be sounding good.  |

I bought one of these: https://www.amazon.co.uk/dp/B0CM47X42Q?psc=1&ref=ppx_yo2ov_dt_b_product_details  It has a few modes: * It can trigger specific MP3s when pins are grounded (they way I use it) * It can trigger specific MP3s and which part using UART mode * (I think) it can also be controlled by SPI PDF data sheet.. DY-SV5W Voice Playback Module Datasheet.pdf My use case is a ghetto sound board linked to PicoMite. Px |

Oh this is soooo cool  and has given me another idea.I can get four of them for ~£10 on AE Using the PicoMite to control them, I bet I could have a multi-track playback device. I might have backing bass on one channel and percussion on another (and then something else on the other tracks) which would allow me to set levels to suit a particular venue. I already have a mini-mixer. I bet that they would stay in-sync at least for the duration of a song(?) |

Unusual nowadays. There have been circuits that did that, but not for many years that I know of. However, what you might not be able to do is to connect the speaker from one side of a differential output to ground. The output has to be between the diff outputs of a bridged output as there may not be an isolation capacitor.
