Thank you, LyleHaze, for your quick response and your suggestions. I use a small Palm Vx to operate the dout card and "fiddling " with this is definately a non starter. It takes a hair dryer to even open it as it's glued together ! I looked at your links for sequencers and it seems that they are software devices. I can use cakewalk to play the files and alter the tempo 'live' but I really need something to respond to an external, mechanical / electronic signal. It seems that another type of player is needed. I have been looking at the SD Card reader player which is an open source device on the web. Maybe this can be tweaked to produce the desired effects. Thanks again

I now hava a good dout card using midio128 and have applied this to my pipe organ with the aid of some solenoid valves in the wind chest. I now want to vary the speed that the midi tune is played either by a varying voltage or varying frequency pulses. With this, I can make the tune respond to the speed of the crank handle for the bellows. I'm not sure if this is a function of the midio128 program, or whether I must look to the player system. I know the commercial organ systems can do this. Does anyone have any ideas on this ?

to stryd_one Your first comment, "Step 1 - Talk to Nokia", proved to be the answer. I downloaded and installed the latest version of the Nokia Suite and all the problems have disappeared. When I check the properties for the Mios Studio exe file, it now shows the original two java options, platform and 2 platform, but now shows the nokia suite as a third option. Thanks for your help.

Thank you, stryd_one, for your comments on the Mios Studio / Nokia problem I have. I checked the start properties for Mios Studio and it seems there are two options for java. One is standard and the other is 2 platform ? Mios Studio runs on either of them. When time permits, I will re-install the nokia and see if each program will run on a different java option. I don't know if the two options belong to the original java installation, or if the nokia install put one of them there.

I've been running Mios Studio and MidiOx successfully, for several months, on XP_Pro SP2 and have had no problems at all until........ I installed Nokia suite for my 6288 Mobile. This also, apparently, runs under java. Now, everytime I try to load Mios Studio, I get, guess what...Nokia Suite. The only immediate answer I could find was to uninstall Nokia. Anyone got any Ideas ?

Hello T.K. Thank you for all the help you have given with the note off problem. It now works fine, turning everything off on receipt of #CC123. My first thoughts on using the new GPUtils was utter confusion, but after some rational thought, it now seems to be doing what I want. It seems, from looking at some of the other Perle scripts, that it might be possible to convert syx files back to asm. This would be useful for checking the scale and options when there are problems. Could anybody offer some guidance on how to achieve this ? I tried to follow the same proceedure as for making the syx file, with 'Make' but all I got was....................... Regards - Busker99 Ian

Hello T.K. Yes, If you can modify and produce a new asm file, I can recompile the hex. Ideally, It needs to turn off all notes on all channels on receipt of a #cc123, with a value of 0. Would be great if it could also responded to a #cc120, of value 0. Thank you, once again, for sharing your time and expertise with us all. Regards Busker99 - Ian

Hello Chris, Yes I had noted T.K's reply. According to most of the geeks and pundits on the web, it seems that the midi standard is not rigid and many manufacturers interpret the control codes to suit their own convenience. However, the SD player sends it's control codes with a zero value, according to the cakewalk "logging" I received from John Smith. I will get him to confirm this. It would seem that the answer is for the SD player software to send individual "note-off" commands for all the notes playing, before it pauses, just like all the other equipment I have tried. The other (Commercial) midi card, by Omega Electronics, does respond to these commands. So, we still have the problem it seems. Regards Ian - Busker99

I must thank you for your time and effort T.K. I have managed (eventually !!) to master the minefield of compiling the new hex file, with all the necessary utilities, I then applied the new sysex patch, created from the MK_Midio128.ini file, and the core will now respond to #CC123 to turn the notes off. But...... It will only turn off the notes for the one channel it is set for, and it seems that the #CC123 must be given a value of > 0. Is this the case ? Regards Busker99

Thanks for your time anyway. I'll repost it in the asm section.

Thank you for your reply David. However, I have no knowledge of the programming necessary and can only approach the problem from a "common sense" Point of view. I am using MIDIO128_v2_1d. Could you please show the necessary code and indicate where it should be included in the MIDIO128 main.asm. I can then create the new hex file in MPlab.

Many Thanks for you rapid reply Thorsten. Yes, on "pause" or "stop" the SD player sends a CC7B (#123-All notes off) for each channel, followed by a 78 (#120-All sound off) for each channel. Can midio128 be modified to respond to this?

Have just finished an integrated core and 64 note d-out board for my midi pipe organ. All works fine on my PalmVx, midi keyboard, Casio FDD player, cakewalk etc. However, I tried it on the SD Card midi player. If the pause is pressed, it stops playing but does not turn off the notes that are playing. I have tested all the equipment on MidiOx. This shows that all the players send an individual note off when paused, and then a block of control codes. With the SD player, it just sends the block of control codes. This works fine on a commercial J.Wale midi out card. Can the midio 128 be coded to accomodate this?

Thank you for the link Michael, I'll go and have a look. Following Thorsten's advice, I now have the Dout module working well on any notes and channels I choose. Tonight, I've just finished making the 32 note Din module. (More ferric chloride stains everywhere !!). It works fine but I get some odd results when I try to show the input to the core on the Dout module. Time for bed now so it will have to wait until later today. Thanks again

Many thanks for your help, aspecially for the lightning response. Will now go and give it a try
