Pianoteq XRuns

Using Zynthian
5

Hello @thefunkyjoint,

you could ask Pianoteq customer service to provide you with an older not so resource hungry software version.

Greetings and God bless, Marius

You can set the internal sample rate to a lower figure by editing “/root/config/Modartt/Pianoteq66 STAGE.prefs” and setting . [EDIT] This does not always work. I haven’t figured out what makes the application pick up this config or return to some default. Maybe it is related to the demo version.

Setting internal sample rate to 11025 will reduce the bandwidth to 5kHz and make the piano sound rather dull. It is already band limited to 10kHz which is not great. I look forward to a time when we can play with internal sample rate of 44100 but I suspect that isn’t in the near future!

Jack buffer size of 512 will give 23.2ms latency which will be quite noticable and likely difficult to play well.

Does anybody can suggest a specific version ?

Well in any of these cases i would prefer to live with the XRuns :frowning:

I can get a Pi4 on my city for a reasonable price. How hard is to do this upgrade using the v3 Zynthian kit ?

10

Um…

I used an electric drill. (I took out the electronics first.)

Aside from the case modifications, is there anything tricky about replacing the board itself ? Are all Zynthian’s components compatible with Rbpi4 ?

12

Yep, just the holes in the case were wrong. Everything else was the proverbial plug and play.

13

Nice ! Even the same Sd card image will run fine ?

Which Rbpi4 model is enough ? 1gb RAM will run Pianoteq fine ?

14

I think 2GB is the optimal investment :wink:

Nice , i just bought a Rbpi4 2 Gb ! :grinning:

Does my curent SD card image will run fine after upgrade or do I need to do something ?

16

If your SD is Buster, it will work out-the-box. You don’t need to change anything.

17

Sorry for the ignorance, but what means the SD is ‘buster’ ?

18

What is the name of the SD image file you are using?

19

This is the file name i used : 2019-06-26-zynthianos-stretch-lite-1.0.0-RC3.zip

This image is not compatible with RBPi4. You should use a newer Buster image:

I dont need the HDMI ports, so i only need to adjust the microUSB power source ?

22

I don’t need the HDMI ports either, but they sit proud of the case so you need to make room.

A regular electric drill will do the job ? Is the case very hard ?

Does this image work with Pi3 or only Pi4 ? I’m asking because i flashed it and tried to run it on my Pi3, but it’s turned on for 10 minutes now and the although the screen seens to be turned on, nothing appears on it.

EDIT : I went to webconf and changed the kit to V3 (it was on V3+), and it worked… :stuck_out_tongue:
When i upgrade to Pi4, should i set it back to V3+ ?
