Synth cutting out & Load time problem...???

[Hlis93]

Hello,

I am having some problem with the first Projects that I have been working on.

1. I loaded them in my VST folder in Cubase and ended up with dropped or shorted notes when playing in a loop. I opened them in Cakewalk’s Kenetic 2 and Ableton Live 4 and did not get this problem however.

2. It takes an incredibly long time for them to load (even after the initial install), changing between presets brings the whole thing to a stop. I also had this problem in my other sequencers.

3. Some of the presets cut out when I play a chord, I checked the volume on my project mix and that was fine..I didn't overload the CPU either. I have the voices set to 32 although changing that didn't make any difference. Any ideas?

I am assuming that I have not constructed them correctly or there is something that I have configured incorrectly (perhaps the whole thing). I did try to search this out in forum. I didn’t come up with anything but that maybe that fact that I don’t know the proper keywords to describe this.

Heres the OSM:

under OSM Synth Questions.

Thanks Hlis
PS any suggestions on what I done wrong in the OSM would help.

Question: what CPU are you using?

Will have a look at the schematic later on if I get some time left over for it!

[Hlis93]

I am using an E-Machine with an AMD 64, 256hard drive, 1 gb memory. I have this problem even with the example synth.

Hm. Ok. I don't have the possibillity to test this right now, but I have tested lots of different schematics in Cubase SX when I've had access to it several times. Any other SX users here that could help Hlis93 out?

I download wavedraw by AM and pluged that in. The same problems occured. Cuts notes off (make a little click) Then nothing till the next note.
Not sure if it is my sequencer (Cubase SL3 w/latest update) or something else. Test all my plugs and it did not occur with anything else. This sucks. If I do eventually make something cool that I want to then what....Honestly, any Ideas. I am going to try and reboot Cubase again.

Thanks

Back again,

I spent some time fixing some problem areas in my OSM thinking it might help and it did. Reduced CPU load and some wrong connections. However, the Load time problem still persists for these two Synth’s I made…incredibly long and to change a preset is devastatingly long.

Clean install of Cubase SL3 and all drivers from my outboard equipment, the problem of notes getting cut off when in Loop play still exists, I also noticed that if I start a song from the very first measure without the loop it is cutoff as well, a bit irritating when using a bass sound, completely infuriating when using a Pad (it Drops this off an entire measure or however long it is till the next midi events retrigger the synth), completely unacceptable if I going to export a song.

This is NOT JUST MY SYNTH’S that I made to experiment with, but on anything that is SM. Exported several examples, even the example synth and some plug’s by AM they all cut off with a little click. I tried on another computer same thing with Cubase. Is it Cubase my install disc? What is it?

I NEED to fix this but I don’t know what it is that is causing it. No other plug that I own does this including free and commercial. If I can’t fix IT there is not point in using SM, complete and total Loss for me.

…Must just be me!


Sorry if I seem a bit upset, but I am very discourage right now!

Hi Hils I have exactly the same problem with my synth.. It freezes up for a while when I change presets and also it does the same when I press play in my host. I am using the laptop version of the amd 64 chip i.e. turion 64. Maybe its gotta do with the chipset I dunno.
Btw Dev's If you want a copy of my synth for testing lemme know and I'll e-mail it to ya.

[Hlis93]

Thank you for the reply. What to do now however? I am finding another computer to test this on. I have an old windows 98 and a friend has a Dell with intel will try this weekend. See if its just AMD????

Perhaps Cubase is Screwed up as well. I noticed that when I tried to Select a voice from Yamaha Motif ES with this bank select function that it also drops and cuts off notes in loop and liner song play as described above. Never really used it due to the Multi-part ed. I didn't know till now.

Perhaps is all this above Can't tell.

I load a an updated version of my synth experiments, but I found this post and I have to ask about very simple and direct post that could help with this:

"One of the things that i don't like about plugin making is that you have to learn how to optimize your stuff...but unless you learn how you may well find alot of bugs and slowdown, theres also clipping sometimes with various things and you will need to learn how to get rid of this also, sorry for sounding negative everyone im just in a very honest mood today. Things have got much better though and are always getting better and as Sm is always getting updated all it will take is time or a bug report and things will get sorted"

Thanks

Hi Hlis93,

I'm looking at this for you.

The loading time and preset changing delay is very strange. It loads fine and changes really quickly inside SM. So the problem only seems to occur in the exported plugin. Do you see it working fine in SM too? I think this must be something simple but I don't know what yet.

I'm trying to understand the problem with notes when looping. Are you now saying it cuts off on each note regardless of whether you loop or not? How sharp is the cutoff, does it just kill a note dead or is it something subtle at the end of the release? Does this only happen in Cubase ie. in other hosts is it fine? Also, which preset are you using?

For the chord problem can you give me an example of which preset cuts off when you play a chord? How many notes do I need to play? Do all the notes cut out completely?

The quote you posted I believe was from Tom7777. You don't have to know how to optimise but I think it goes without saying that you can't expect to throw a whole load of things into the pot and get something out that is really efficient. I wouldn;t worry though, you don't have such a problem - from what I can see your two schematics are pretty reasonable on cpu

@Electrogravity - please do send your synth through. Are you saying that you get notes cutting off too? What host are you using?

Sorry for all the questions - the more info I have the better.

Thanks

Ok, pretty sure I know what's causing the slow loading and slow preset changes. It is something simple, I just need to do a few more checks to confirm that I'm right. If I am then anyone using the wave osc would in an exported plugin would be having the same problem. I'm surprised it hasn't come to light until now.

Anyway, will get back to you very soon on that one.

[Hlis93]

Ill do my best to explain this...

"With the Loop on". Cubase allows me to loop a segment of meassures or whatever I have set it to loop and then...well, when I press play it just loops while I am playing something or work on tweak a sound or whatever. Fairly simple.

OK. What happens is that the "cutoff" note ussaully the very first one makes a sharp click and then is silent the next note will pick up again and play till the end of the loop. Then it occures again. With a more sustained note that last say more then a 1/4 note it just does not sound at all when the loop resets to play from its start posistion.

This only happens in Cubase for me but that is my main sequencer. Seems really odd to me. But I am fairly simple, I am sure there is a reason.

And yes it play extremely well inside of SM. Hence my disappointment when I went to use it. By the way it didn't drop out on the exported audio.
IF I draged the song back a full measure?????? If I did it from bar one it does.

On the positive side however, I love this program! I have used reaktor for a year + and have not been able to do this much with Gui. Nor Create sounds that I like. Not that reaktor sounds bad in anyway. Just didn't feel right. I have no idea what I am doing yet but I like it so far. Dont want to give it up just yet. Thanks to every one for the post on the forum with examples of how to accomplish things its a big help for those of us who feel and are a little overwhelmed by this and need some place to start learning. Great examples.

Ur, umm... I think it's come to light before

"I get reports of lockups when loading the table synth..."

[malc]

I was talking about the issue with the wave osc not the issue of slow preset changing itself. The symptoms are very similar but the cause is quite different

[malc]

Ok, give this a try. Download a new vst.dll from the follwoing link:
http://www.synthmaker.com/docs/uploads/2006/sep/23/vst.dll

Go to your SM install folder, make a copy of the existing vst.dll and then copy the new one in.

Now export your plugin(s) again and try them out in Cubase. Hopefully you'll see a big improvement in load speed and the looping problem should be gone.

Let me know how you get on.

Malc.

What do the mean by "wave osc" and what was the problem?
