bourniplus Posted October 13, 2015 Share Posted October 13, 2015 Hi everyone,the B right below middle C on my PC3 sounds noticeably louder than its neighbors. It seems to have the whole range of velocity available, however it sounds as if when I'm expecting a velocity of about 30, it sounds like it's about 90, as though it has a different velocity curve, no matter what the patch.Any thoughts, suggestions?thanks in advance,Martin Quote "Show me all the blueprints.

RudyS Posted October 13, 2015 Share Posted October 13, 2015 I am no expert, but I expect a bad/dirty key contact. I have never cleaned the ones in my pc3, but it should be doable. I did it wit other boards and it was fairly easy. pc3 is fairly easy to open up. Quote Rudy Link to comment Share on other sites More sharing options...
johnchop Posted October 13, 2015 Share Posted October 13, 2015 It seems to have the whole range of velocity available Meaning you checked the output via Master > Utils > MIDI? If not, that should tell you what velocity the key is outputting. Second RudyS on this: dirty key contact. Quote I make software noises. Link to comment Share on other sites More sharing options...
bourniplus Posted October 13, 2015 Author Share Posted October 13, 2015 I just checked with Master > Utils > MIDI and indeed, it looks like all the values are available, but it's hard to get anything precise between 1-50, as soon as I play harder than pianissimo it gets in the 50's.

Dave Weiser Posted October 13, 2015 Share Posted October 13, 2015 Does it happen on ALL sounds? Is it only on piano sounds? Try testing it on a few different types of sounds - bass, synth, strings, percussion, etc. Quote https://www.theboywhowantedtorock.com http://www.weisersound.com https://www.facebook.com/weisersound Link to comment Share on other sites More sharing options...
Al Coda Posted October 14, 2015 Share Posted October 14, 2015 the B right below middle C on my PC3 sounds noticeably louder than its neighbors. At least, you could play part-1 of "One Note Samba" and in E A.C. Quote Link to comment Share on other sites More sharing options...
bourniplus Posted October 15, 2015 Author Share Posted October 15, 2015 Well, I cleaned the contacts with isopropyl alcohol and the problem is gone. The longest part of the job was putting the strips back in place properly, this probably takes 20 times the amount of time it takes to remove them! Thanks again to all.

bourniplus Posted May 13, 2019 Author Share Posted May 13, 2019 Resurecting this thread because I had pretty much the same problem with another note, only worse. When I googled about it I stumbled on this thread. Funny thing is I didn't remember about the thread or even about the fact that I previously had that problem. Once again I opened the keyboard, cleaned the contacts in the rubber strip and now everything seems ok. I wonder how these contacts get dirty? This keyboard litterally spends its whole life in its case, besides 1 or 2 gigs a month... edit: putting the contact strip back wasn't that bad, what's wrong with you, me-from-four-years-ago?!

Your case isn't hermetically sealed, and these things happen over time, not suddenly, although things like outdoor gigs definitely exacerbate the problem.

Yes, and also those contact sheets where off over time and need to be changed. The way they work is there are 2 points of contact. An initial one and secondary one. The velocity (loudness) is determined by the time between the initial and second contact. The harder you strike the note, the smaller the time interval and therefore the louder the note. Those contact are made of rubber and eventually they crack or the resistance of the rubber becomes too light and therefore the time between the 2 contacts is virtually zero and therefore the note velocity always goes to 127. That's why the note seems louder. Bring it to any good technician to get changed. Usually when one starts to go the rest will follow, so a good tech will do a thorough check up and change as many as necessary. You're in Montreal so if you need a recommendation for a tech I could give you one.

bourniplus Posted May 15, 2019 Author Share Posted May 15, 2019 Salut Ian, I'm not in Mtl area but thanks for the offer. Since it's happened only twice so far I'll keep cleaning them when it happens again, until it gets too frequent. I've once replaced all the contacts on my Roland controller, but I don't think it was a velocity issue, I think the notes were just dying one after the other. Quote "Show me all the blueprints.
