Mono Firmware V2.0 Thread

I did implement the feature but didn’t enable it on the beta.

One thing is for sure, once you start an upgrade, either you have the new firmware or you have nothing at all, as the firmware update wipes the previous firmware before doing its thing. So my guess given your video is you had a weirtd corruption during firmware upload! I will dig into it but know that 5 of our beta-testers have successfuly updated to this beta version, on the 3 platforms with the recommended and tested sysex software … I wouldn’t have claimed it was stable if it wasn’t the case :slight_smile:

Can you drop us an email so that we can discuss and find out what’s going on here : contact@norand.io. Thanks!

@Mathieu Of course the cutoff should do that, that makes perfect sense, just me being slow! I’ll have another go and drop you an email if it still refuses to work. Thanks!

I think I have found out why your experiencing this freeze at boot! It’s a calibration thing … totally my bad, I’ll fix it real quick !

For the note led ping at boot, I’m a bit to blame here it was not the case on V1 and it’sd not written anywhere in the patch note, :slight_smile:

This happened 4 times, 1 time starting from v1.99, 3 times starting from corrupted v2.0b3, and each time the sysex transfer was declared successful. It was only by redoing the entire procedure (->1.99->bootloader v2->2.0b3->clean that the update ended up being done correctly at the 5th attempt (and all operations were performed with the same PC, the same configuration).

I think a survey is necessary: who here managed to update his machine the 1st time and without difficulty? Even better: who on this forum has simply managed to perform this update? The only posts following its publication mention various problems. I am clearly not an isolated case, and this while I voluntarily reinstalled zero (as new) to precisely avoid the sometimes hazardous version jumps.

Whoa, that’s quick thinking @Mathieu ! I’ll have a look as soon as I get home from work and report back after that.

The reason for that is that most people that successfuly updated simply won’t come back here :slight_smile: We need to solve your issue though, could we jump to a private conversation to pinpoint your issue ? You can contact us via contact@norand.io

I have replaced the file on the archive :
Download

Can you let me know if that solves it ?

Will do, as soon as I get home to my mono! :slight_smile:

Using the latest replaced firmware from Mathieu I did the following steps:

1.) Sent it mono_V1.99.syx … After this, steps 1-16 and Pattern were flashing. I let them flash for a few minutes, but nothing happened.
2.) Power Cycled
3.) Sent it mono_secondary_bootloader.syx … After this it began 3 pass auto-calibration and rebooted itself. Pass 3 takes the longest.
4.) Hold down Tempo+Function and send it mono_V2.0b2.syx …After this, it runs a new Auto-calibration routine while the step LED’s indicate status. At the end of this, all step LED’s remain lit.
5.) Then “Clean Memory” boot via F#+G#+A#+Follow+Power … this shows Step LED’s gradually 1 through 16 and reboots automatically.

Norand Mono seems to operate as expected now.

Big thanks for the update, @Mathieu! The new firmware is now up and running over here. The new file did the trick for me, no more freezing during calibration.

how long does the auto calib after step3 take and does it light any lights while doing this?

Step 3 above where I listed “auto-calibration” the LED’s cycled through the first two times-- the sound on output was almost a SAW wave rather than a Sine wave — and the last pass (Sine wave) was about a minute, then it rebooted.

@Matthieu :
As requested off, and as a test, i performed the update from version 2.0b3 R1 to the 2.0b3 R2 patch using the “as new” procedure:

  • Downgrade to version 1.99 using bootloader v1
  • Internal memory purge (F#+G#+A#+FOLLOW)
  • Installation of bootloader v2
  • Installation of version 2.0b3 R2

The operation was a success from the 1st time

Sustain always at fixed level ~60-70% (pot no effect)
Can any one confirm ?

Yup, I’ve experienced a couple stuck notes when physically playing the buttons.
Power cycling is the only cure.

I mean. The SUSTAIN pot simply has zero effect on the sound. The led is always on and at same brigthness no matter the position.
flashed ‘not as new’ and on mono_V2.0b3

-edit-

Seems like release has no effect on envelope either. If acts like an AD/AR envelope (wich is fine btw)

Yes, same for me, Sustain has no effect (installed as new).

Haven’t upgraded yet. Can we see the firmware version with 1-16 as we talked about in another thread?
