MIDI I/O on Pulsar I Too Slow

Hello,
I tried to use the MIDI in on my Pulsar I but it is too slow. What's the deal with that?

To play what?

Music.

My hands are very fast. It's a blur.

'Speed' doesn't mean 'accuracy'.

what instrument? what path? Scope synth? Vst?If you are not a bit detailed it's hard to find an answer...

Direct to the Creamware synths routing it through Cubase 4 using the Novation Remote 25 as a controller. It doesn't really matter since I can use the USB on the Novation instead of a MIDI cable. I was just noticing that the latency was so poor, I wonder why they even bothered to include MIDI in the Pulsar. Is it the same problem on Scope cards?

Never seen that on Pulsar1, Pulsar2 or Scope cards.
If you really think it's a problem, how about actually quantifying it by doing a latency test to see what the measurable latency is?
How about eliminating all other factors, like the host (Cubase) for example.
Of course this is all moot, because it's fairly obvious you're just trolling again

Eliminating the host is a mute point since the host is present when I use the USB interface too. You probably just can't play fast enough to notice it or worse maybe you are a guitarist which accounts for your very aggressive and hostile tone with me.

You seriously don't think there's any possibility that the driver for the Novation is configured differently to the Scope one?

Ok genius, perhaps you could direct me to the MIDI latency configuration window so I can uncheck the box which slows it down to "unusable mode".

FWIW, I have one of the really old Pulsar 1 cards, and I used it for years with SoftStep and ArtWonk, two algorithmic MIDI pumpers that can produce MIDI much faster and denser than human hands or feet or whatever. I never had a problem with MIDI on that card, nor do I have a problem with the big Scope cards that replaced it. Scope MIDI works great. So whatever the problem, it's not coming from from the Pulsar.

Well I'm not sure why I'm even bothering to help given your rude and belligerent attitude, but what the hell... maybe you'll learn some social skills some day. Try googling 'Cubase emulated MIDI ports', it's a pretty well-documented problem. I'm not a Cubase user, so there's likely even more settings to look at inside Cubase. The best place to seek help for this is probably cubase.net
Obviously before you pursue these solutions, you should actually do a test to see what the latency is, and also try another host to narrow down the problem. This is basic troubleshooting practice.

you might be a drummer
anyway, I have a few Pulsar Ones, too - and I never had a problem flooding the Pulsar midi port with active sensing from my old Kawai K4 under Win98
in XP you can immediately crash the machine with that method - now who's to blame ?
adipose code like Cubase isn't really worth commenting

Cubase is quite good now. I don't have any problem with it. I wish I had a dual core Pentium but it's very stable for me until my projects get very large. I hated it for years but now it works fine. I don't use Logic because Apple screwed Emagic users by dropping pc versions. For this reason I hate Apple and because Apple users generally are a-holes with Steve Jobs leading the way.

there is a tiny bit of latency introduced by the keyboard, another one by the Novation Midi driver, next is Cubase communicating with that Midi input, and finally the output to the Scope Midi driver.
direct would be the keyboard connected to the Scope card...
Midi (in it's original form) is a fairly slow protocol - even a pure hardware 'through' connection can have 5ms of latency.

yeah did you try to connect midi source directly to your synths ?
you can always feed the midi signal back into cubase to record right ?

Been running all kinds of MIDI configurations on my old Pulsar I (going back to before I got the Scope Pro), and never had problems with latency - in fact I tend to prefer it's response to my older PC's running even Soundblasters

.
Suspect is having too many layers of drivers and/or possibly even an IRQ conflict with the stupid USB. If you're going in via MIDI, then the other layers are possibly suspect - although they shouldn't be. If you're going THROUGH Cubase, then that's another suspect layer - but not sure.
Yeah, test the controller direct into Pulsar I with maybe a simple Scope synth and see what happens.
It shouldn't make any difference, but you can try changing the latency settings in Pulsar configuration.
