Re: RS232-Midiplayer und passender USB-Treiber

Hmmm. If I understood right: If I do nothing (except sending nothing) - a short note will continue and die after its normal life-time - a continuous drone will live forever If I send "all notes off" - a short note will die immediately - a continuous drone will also die immediately So I think, the f...

Re: RS232-Midiplayer und passender USB-Treiber

So my current solution is to let the sound (and the drones :wink: ) go on during PAUSE ... In theory I suppose so. But the short duration type of notes IE piano,guitar etc will decay very quickly until new note information updates them plus not all drones will play continuously. depending on which ...

Re: RS232-Midiplayer und passender USB-Treiber

Hi Siggi. The stop start continue codes are really for synchronising multiple midi units to a common clock. I'm assuming you have a way to stop the song at a given point then restart it? If that is the case then rather than sending a reset message when this key is pressed just send an all notes off ...

So, ich habe jetzt auch mal ein Video aufgenommen, wo der Zeddy ein Midi-Stück abspielt:

Re: Zxpand+ with Midi.

Hi Moggy does this timing problem also affect the conversion from midi format 1 to 0? I need at best that format conversion for my player, not via CSV files. Apologies again Siggi I forgot your player uses the real thing not a conversion. :oops: From a format point of view regard type 0 as a stream...

Re: Zxpand+ with Midi.

Good to hear the player is now correct and apologies over my confusion about your player reading multi tempo,I confused it with the Xpand player which is single tempo only. :oops: One thing I have to confess is that never having needed to use a converted file before (CSV) only midi files. I have fou...

Re: Zxpand+ with Midi.

Hi Siggi. Your problem is a simple one so don't get too hung up on on technobabble re quarter notes etc. If you like I can go into which method of pulses per quarter to use for a given file and lots of other unwanted crap or just cut to the chase. Firstly a midi file with no tempo information is not...

Re: Zxpand+ with Midi.

Here are some files by the band Police, whilst not to everyone's musical taste they are in the most part well sequenced (on a Roland sound canvas I think) and sound fairly good. They are listed by catalogue number rather than song title but the titles should be easy to work out. Have fun. :D Moggy.

Re: Zxpand+ with Midi.

Hi Siggi. There are a few ways to look at the problem. This file was part of a larger file with a section of it saved and as these files do not crop up too often my way would be to leave the player unaltered and alter the end of file data figure to a short point after the last note off value and rec...

Re: Zxpand+ with Midi.

HI Moggy I have some MIDI files, that contain a lot of silence at the end (first I thought, that my player is waiting for ever for the meta event "end of track" and could not find it). Is that a result of a conversion from an other midi (or whatever) format? Or just a bug? Here is one of them: CowC...

Re: Zxpand+ with Midi.

Thanks for this Siggi. Firstly congratulations on your achievement.

Some good work there Siggi. :D Is it possible for you to make a recording of diamond just like you did for rhapsody?

Hi Moggy I used the original Diamonds version. The PC runs it at correct speed. So I think the Zeddy cans also do it :mrgreen: I will check my NMI based timer this weekend using a scope.

Re: Zxpand+ with Midi.

Hi Siggi. Many thanks for taking the time for this. :D The reason I chose this file is because the xpand struggles badly with it when converted and I was hoping that your method of playing the file would cure it.

Re: Zxpand+ with Midi.

Hi Siggi. The main problem with the Pink Floyd file is that it is a GS or General Standard file which is meant to be used on Roland equipment whereas what we posses is GM or General MIDI equipment. What this means to us is that some of the note assignments are wrong for GM (They are meant to access ...

Re: Zxpand+ with Midi.

Just a quick reply Siggi. I notice the zip file contains a CSV file not the original MIDI file. I thought the Atmel player used original MIDI file not a converted one? If the original MIDI is now playing slow with the Atmel player then I would guess the data rate is too slow because if the WIN playe...

Re: Zxpand+ with Midi.

Hi Moggy yesterday I played the attached song from Pink Floyd: it is played totally wrong. The "Tempo" setting is processed, but probably not correct. I adapted the timing (I found in the player source) from Atmel 8MHz timing (1 us clock???) to Zeddy timing (64 us clock). But it sounds ugly. I trie...

Hi Moggy I made a .OOG file (USB-Stick->ZX81->Midi->YM->Headphone-Out->Mic-In->Notebook), because my Audacity does not have a MP3 licensed module.

Re: Zxpand+ with Midi.

The problem with a lot of MIDI files is that they don't follow what were accepted conventions of the time and were put together very poorly by composers who should have known better. :( It was always good practice to end a song with a systems message of "all notes off" followed by a GM reset. This s...

Re: Zxpand+ with Midi.

The converter attached here has a German language read me file to help you.
Files can only be done one at a time as unfortunately the batch conversion part doesn't work but I'm sure you can fix that. 8)
