An acoustic piano feels alive and it is probably because of the unpredictable nature of how the sounds unfold. Playing a digital piano that uses samples feels dead. Until recently all digital pianos used samples – recordings of notes played on real pianos. Then of course there is the sound… Physical Modelling One is the control and responsiveness of the action which in the case of the V-Piano is lovely – very Steinway-like. There are two aspects to a great instrument. I was in love! I bought it there and then! Then I played a few more, some classical pieces, improvised a little and then a lot. I visited a shop to try it, played a few chords: it sounded good. Despite the great reviews and excitement around this new instrument which used breakthrough technology, I was sceptical. I hated practising on it and just felt I couldn’t really express myself fully or naturally.Īfter reading a rave review in a magazine, I decided to try a new digital piano made by Roland called the V-Piano. This was OK but I always found that digital pianos had little life or soul to them. I had a decent Roland digital piano with a great action. I thought I would have to buy an upright piano but I find they have an inferior action to that of a grand so didn’t really want one. Sadly, I didn’t have room for my grand piano in my London flat. The fast, wonderfully weighted responsive action of a Yamaha piano is lovely to play but many pianos have rather sluggish actions by comparison… I used to own a Yamaha grand piano which I bought from new and loved for its tonal depth and expressiveness (even more than is usual for a Yamaha) and its marvellously responsive action. But it can be a problem falling in love with your own instrument when you have to play others which often have their own individual quirks. CPU throttling can be done, wifi and X is not a issue any more.I love acoustic grand pianos and spent my formative years practising on very nice ones. You can open application without worries. Pianoteq gives better graph and perfomance index on the same machine. Of course it's also good idea to upgrade your machine :) It seems the special RT-kernel is no needed. If you experience problems with pro-audio applications, give RT capabilities to the relative applications. All those steps are not needed with RT capabilites set. I was using pianoteq for 2 years without RT capabilities, I had some problems and to solve them I disabled wifi, set cpu to freq 1200Mhz-1500Mhz and added niceness to X server. miracle there is more cpu power and no gaps. Here pianoteq with non-RT kernel but with set_rlimits enabled on qjackctl, jackd, pianoteq and jack_capture. Oops, you don't have a html5 capable browser to listen the audio file. 70 No1 three times faster! Not a joy to listen at that speed :) The gaps is because there is not enough cpu "power". To take pianoteq to the limits I played the demo of Chopin Waltz op. Here the sound with non-RT kernel and without set_rlimits. I forgot to keep that "record".Īlso when I used RT capabilities I was able to open ksnapshot without problem in sound. Interesting part was, that when I tried to record in tempfs filesystem (on the ram) with non-rt jack_capture, pianoteq does not liked that. This configuration gives the users that belong to music group the privilege to start (if they want) those applications with RT capabilities. My configuration is /usr/bin/jackd nice=39 rtprio=80 /usr/bin/qjackctl nice=39 rtprio=80 /usr/bin/pd nice=-1 rtprio=80 nice=-1 rtprio=80 nice=39 rtprio=95 nice=39 rtprio=80 nice=39 rtprio=20 nice=39 rtprio=20 memlock=5000000 Interesting findings or bad configuration Start the program with set_rlimits -r PROGRAMNAME Write every program (that supports RT) a line like: /usr/bin/jackd nice=39 rtprio=80 memlock=100000 First option requires filesystem with POSIX capabilities: setcap cap_ipc_lock,cap_sys_nice=ep /usr/bin/jackd You have to repeat for every pro-audio application.There is two ways to start a program (that supports RT) in RT mode. The program suggest to use rt-kernel but in my configuration seems pointless, since the ordinary kernel provides rt capabilities. The program is commercialĬlosed source and it's called pianoteq. I play piano with my slackware installation (13.1).
