If it is true than other brands could be affected too. You say the MIDI event delay depends on the cpu load of the Numa Compact 2? This implies when your keyboard sends delayed Note-Ons then this delay is recorded in Pianoteq. Pianoteq's MIDI event monitor and Streambyter both add a timestamp on receiving. Your MIDI receiver/app adds a timestamp when a Note-On event is detected. there is no "midi time-stamp" in realtime MIDI events sent from a MIDI keyboard. There are a number of organ apps for Ios so I'll use one of those instead of the The Ipod performs very well, so this is a nice addition to my setup. I tested the modified preset with both Pianoteq and the Ravenscroft piano on the Ipod. the Numa Compact has a cpu that is in fact not fitted for the job.Īt least if you want to use it to play an organ and use midi at the same time.įor now I removed the organ from my preset and everything seems to run stable. I repeated my previous steps and was able to reproduce the results time after time. I selected the organ again and low and behold. I started playing and as soon as the jitter occurred i changed the organ to a Piano (sampled). I use a Korg Nanocontrol to select which layer should be active, the pad, the organ, Pianoteq, or a combination of the sounds.
Please let me know if you find the same jitter with any sound selected, as (for instance) the Organ sounds are based on an additional DSP modeling, very demanding (time wise).Įureka! My preset that I always used was made of a layer with a pad and a 888 organ. Off course I wasn't satisfied with this answer and after a few mails back and forward I received a email containing this line: In short: "All our instruments are tested extensively and we never encountered problems like the one you mention, also no other customers complaint about this"
I confronted Studiologic (Fatar) with this behavior and after a few days i got a reply, No matter how hard I tried, I could not make it fail. Midi time-stamp, but at the wrong time! This is called midi-jitter.įortunately I have a Emu Longboard lying around, so i connected this to the Ipod and started testing. Well, my recordings played back fine, so the midi time-stamp is correct.īut, when playing live, the timing is wrong. It seems that Pianoteq is showing the midi time-stamp, but Streambyter is showing the system-receive time-stamp. I will never be able to play 3 notes, with 2 hands, at exactly the same time.īut why didn't I saw this with the Pianoteq midi viewer? Notes should never arrive at exactly the same time. Whats this? Midi is a sequential protocol (note after note). I decided to run a midi monitor(Streambyter) on the Ipod and see if i could find any anomalies.Īfter a while i encountered my usual delays and started to browse the received midi data. Also, there were no problems to be found in the Pianoteq midi events screen too. The only thing from my setup that hasn't been replaced is the piano.īut.I replayed the midi files that I recorded with this piano and they were fine. After just a little while i was shocked to hear exactly the same delays that i heard with Pianoteq. I took the Ipod home and connected it to my Numa Compact2.
The setup on the Ipod was tested extensively in combination with his Nord Stage. I friend of mine was very happy with his Ipad and Ravenscroft piano,

Tired off trying i decided to go for a quick solution and see how to fix my Pianoteq problems later. Now i had my cpu running at max and Pianoteq was running with real-time priorities, but still the problems keep bugging me. The fix for this problem came from Groovy: cpupower set -perf-bias 0. I was running Pianoteq on Linux and my cpu never kept running at max, it was just spiking to max sometimes.
#Ravenscroft 275 recording performance windows#
One important clue was that when running on windows my cpu frequency was at max when selecting the "performance" powersetting. You can read the whole story in the post mentioned before. This made me realize it was worth an other try.
#Ravenscroft 275 recording performance license#
Sometimes a chord was delayed, sometimes a single note, sometimes I could play for hours without any issues.Īfter months of trying I could not find the answer so I was ready to sell my license.īut as soon as I posted that my license was for sale, this helpful community reached out with numerous ideas to fix my problems. To summarize the previous topic, I encountered strange latencies. Somehow this topic is closed so I will post my final post in this new topic, hoping it will serve somebody when encountering the same strange problems as i did. It has been a while since my last post in. When you have eliminated the impossible, whatever remains,
