Seq Vr1.8!

MIDIbox SEQ
1

Dear MIDIBox Peeps,

 

This is my first post. To cut a long story short, my friend built a very nice SEQ for us quite a number of years ago. It did get some use at the time, but I have recently re-discovered it now that I can generate accurate MIDI clock using an Expert Sleepers ES3 & 5 combination.

 

I am really enjoying sequencing on the SEQ but have a few questions. 

 

A) The beast currently has 1.8 firmware. What would be the latest that it might accept? (where would I get such a thing and instructions on how to go about it)

B) I can’t seem to find a version specific manual: Transpose and Hold Mode keeps doing unexpected things. 

C) I gathering build experience on some simpler projects, I see you can get boards for the lite seq, but I would really want the CV and Gate expansions; will there ever be more boards for the V4 full?

 

Many thanks for your time

Hi,

 

 

A) The beast currently has 1.8 firmware. What would be the latest that it might accept? (where would I get such a thing and instructions on how to go about it)

 

I don’t remember that I ever released a 1.8 firmware.

MIDIbox V1 was based on a PIC16F877 - could you please look into the case and check the PIC type?

Anyhow, the documentation for this variant can be found here: http://www.ucapps.de/midibox64seq.html

and the latest firmware (v1.01) here: http://www.ucapps.de/pic16f_firmwares.html

 

If you find a PIC18F452 inside, then it’s probably a MIDIbox V2

Documentation: http://www.ucapps.de/midibox_seq_v2.html

and the latest firmware (v2.4f) here: http://www.ucapps.de/mios_download.html

 

 

B) I can’t seem to find a version specific manual: Transpose and Hold Mode keeps doing unexpected things. 

 

yes, the old documentations only show the latest state.

This has changed with MIDIbox SEQ V3 (and upwards), where the documentation is hosted on a subversion server, so that the history is available.

 

 

C) I gathering build experience on some simpler projects, I see you can get boards for the lite seq, but I would really want the CV and Gate expansions; will there ever be more boards for the V4 full?

 

Most PCBs are available here: http://www.midibox-shop.com

 

You need:

  • a Core LPC17 PCB

  • a SEQ CS PCB (also called “Wilba’s Frontpanel”)

  • an AOUT NG PCB (for 8 CV outputs)

 

For the gates you’ve to build a 74HCT541 based output buffer circuit on vero board as shown here: http://www.ucapps.de/mbhp/mbhp_core_lpc17_output_buffers.pdf

 

Best Regards, Thorsten.
