The videos I have seen on booting from ssd all say that it improves boot time. Not so worried about sf2 times, but multilayer sfz soundfonts play from disc in Linux sampler… I think that will be the biggest gain
Raspberry Pi’s big problem is the lack of a SATA port.
Linuxsampler does not fully load samples into Raspberry memory, but loads them at runtime, as needed…
the more samples are used in the instrument, the more crack when playing samples occurs.
Especially a lot of these problems arise when using a flash drive and sfz … As you know, the speed of reading from flash drives decreases with decreasing file size and increasing their number.
There are less problems with stuttering when using GIG samples …
Interestingly, on raspberry pi 4 with its usb3.0 port and corresponding flash drive, there are fewer bandwidth problems??
That’s what I’m hoping @Roma … I am currently using a pi 3, what has these stuttering issues every now and again. I hear that an emmc ssd on a usb3 port will fix it.
Btw, I am not even remotely interested in sata on a pi… I read that some emmc drives can do 3,500 MB/s so I’d go straight for that and forget sata. For comparison, a class 10 SD card reads at 10 MB/s
Perhaps a RAM disk (with 8gB to play with it wouldn’t be too much trouble) - where the sampler data (SF2, SFz, GIG or whatever) is copied from slower storage for performance use.
Would require some tweaks to Zynthian OS… but nothing too difficult.
As I know, linuxsampler uses save memory resources technology similar to that which was once used in Gigasampler and Gigastudio … The company “Native Instruments” now calls this technology “DFD” - Direct From Disc and uses it in its sampler Kontakt.
The technology is beautiful, it allows, with a small amount of RAM, to use instruments that are large in volume of samples…
Disabling this function in linuxsampler seems possible?
Am I right in assuming that the boot time will increase many times as the throughput of flash drives remains the weak link in the system?
I think about replacing pi3 with pi4, is the game worth the candle?
Which sound card are you using? Have is it been good enough to allow you to reduce the sample buffers? Going by previous discussions, social distancing with real musicians would mean that they are a minimum of 6ms latency away from you… How virtually close is your zynthian?
