    Hi, I having problems while bouncing. Those started few months ago, but I dismished them and I simply bounce again. Track after track is showing me that here is something weird. Today I was rendering a song that wasn’t finished to test it in DJ desks. I’ve bounced it three times because always there is a fail. Sometimes a generator randomly stops it sounds (usually Phoscyon, and I think it has a bug), and other times there is timing issues. Take a look to this picture:

    I don’t know if the problems are Podium or plugins related. What I know is that Phoscyon (and maybe other D16 plugins) can stop it sound if there is a tempo change in Podium (however in this song there isn’t any). I didn’t tried in another host, later I’ll install any demo and I’ll test them in anoter host.

    Anyone are having these issues?

    edit: I just installed Orion to test tempo change problems, and it’s a problem that only happens with Phoscyon and Podium, when you’re playing a long track and you do changes in the tempo. Should I contact D16 about this problem?

    Besides tempo changes, do you, by any chance, use zPitch or any other plug-ins that produce latency? That’s the most common reason I’ve found so far when there were errors in my bounces.

    Does the tempo change problem also exist if you use realtime bounce mode?

    Hi, I explain all my problems with more details rendering constant tempo songs (no tempo markers except the first one):

    – Sometimes after bouncing I discover that in the rendered audio a plugin (usually Phoscyon) stopped its sound in the rendered audio. This a random thing, and I’ll say that it happens 1 each three times, with 2 instances of Phoscyon (used as ext. mode) in the song.

    – Other times, after bouncing, I see those timming issues that I show in the picture, they’re random, and the happens once each 3 times too. And yes, I’m using in that song two plugins that create latency. Decimort in the Drumazon (delayed) track, which generates around 1ms of latency. And EventHorizon in the master channel, which generates around 50ms of latency.

    – While playback (not rendering) I don’t have any problem with Phoscyon, except when I want to change the main tempo of the song. When I change the tempo, via double clicking toolbar’s tempo dialog, while the song is playing, and frecuently Phoscyon (used in ext. mode too) collapse and stops it sounds. This didn’t happen in Orion, and the easy way to reproduce this bug is write two or three long track with Phoscyon (not use looping in a small clip but you can use tons of phantom copies if you wish) and change the tempo while Podium is playing.

    It seems that bouncing in realtime doesn’t have any timming or phoscyon mute problem (constant tempo song, I didn’t write in my whole life any song with different tempos).

    Frits, I don’t mind send you the project, it uses only few plugins (Event Horizon, Decimort, Simplon, Devastor, TAL dub delay, Drumazon, Phoscyon and Poise with embedded samples), but if you don’t own Drumazon or Phoscyon (only their demos) you couldn’t set them in ext. mode, due to demo limitations.

    There is a problem with bouncing bypassed latency plugins, which I’m looking at for the next release. The problem can be avoided by setting the bounce on an effect track that doesn’t have a plugin assigned.

    I don’t own any of the d16 plugins, but if you can recreate the problem with other freeware plugins, I’d very much like to receive the project file.

    But I didn’t have any bypassed plugin when I bounced ❓

    Then your problem is probably not related to the bounce issue I’m currently working on.

    Sounds like the plugins you experience randomly stops during bouncing, are all tempo synced? Do you have other tempo synced plugins that you can bounce without problems?

    I’d say it’s definitely related to latency-producing plug-ins, then. Allow me to bump this video: http://www.youtube.com/watch?v=7PBYJj9psos

    I’ve also had it mess up the timing instead of dropping the sound completely sometimes.

    Frits, you might want to examine my old Nucleum example project (Podium Universe), where the same thing happens. The kick drum hit at bar 52 is always out of time when bouncing. There’s a zPitch instance on the master track, and removing it fixes the problem.

    They can be tempo synced, but I don’t use that function in this song (ext.mode means that I use the Podium sequencer instead plugin sequencer). Anyway I’m going to contact D16 about those problems, maybe they can say something. They are on holidays so we’ll have to wait a little for their answer.

    And yes, it seems like thcilnnahoj video.

    I’ve grabbed a shortcut to this topic, and will examine the latency issues at some point. Right now I’ve got my hands full with the mixer update.

    Thanks Frits. Anyway I discovered that tempo changing while playing could be a Podium’s bug. What happens with every (heavy on midi) project is that play cursor jumps backwards or fowards causing a little shuttering, and if this happens while a note is playing then the note will keep sounding.

    So phoscyon, monophonic synth, keep playing that note and the new ones, which will be slides with the same AMP ADSR env, won’t sound. You can try this with any synth, just change the tempo from 140 to 110 or viceversa.

    I’m just adding info to help you to track the problem, not pressuring you to fix it now:

    With drastic tempo changes the play cursor does a biiiiigggggg jump in the time, it doesn’t matter what plugin are you using.

    Playing Phoscyon in int seq mode (you can test this with the demo) and ext sync (just unckeck int sync) and doing a big tempo change does that Phoscyon doesn’t get informed about new tempo and it continues playing to its own pace 🙂

    I notified this in D16 forums too:

    I assume the problems you mention about tempo changes, are when you adjust the BPM value of a tempo event during playback. This currently causes the play cursor in Podium to jump. I’ll improve this in the future, so that the tempo can be adjusted in realtime without problems. However, tempo changes made with tempo events on the timeline should not cause problems. If you have problems with that, let me know.

    Frits, I have a new musical order for 1th January 2011. Please, could you fix before January the latency bug? I say this because I cannot render to wav any song!

    Please don’t feel pressured about this, if you feel that you cannot fix this soon just let me know and I’ll make the songs in another host. 😉

    Best regards

    Did this get fixed ?
