Hi, It might be an good idea to make MIDNAM files from the Sonatina SFZ library. MIDNAM instrument files can be used in Ardour 3. I found the scripts of the Openoctave team, but I've no knowledge about orchestras, the amount of violins needed etc. Here are the scripts: https://github.com/johnsen/lscp2midnam I know more or less how they work \r

Simple sampler/tracker or similar?

by Arve Barsnes

For a quick project (trying to get something finished by the holidays), what program would you people recommend that I could learn in a very short time to create short patterns (like how I would create a song in hydrogen, only the patterns you combine to make a song are samples instead of drum patterns)? Something I could then export to wave or sync directly with ardour. I don't have any midi capabilities at the moment so it would really have to be all samples and "piano roll". Any suggestions welcome! Regards, Arve

hdspmixer oddities

by Brent Busby

There are a couple of assorted manifestations of weirdness I've been living with in the hdspmixer utility for RME cards, but I'm starting to wonder if it's just my system, or whether it's true everywhere... The important one is that the preset saving facility doesn't seem to actually do anything. You can store your mixer settings to a preset file with .mix extension. You can even make it the default file so it will be loaded when the mixer starts. But it doesn't seem to actually do anything. I know it *thinks* it's working because the title bar of its window shows the name of the default preset file I created...so it *thinks* it loaded it, and it does the load automatically when the program starts without me having to do it...like it should. But actually, the settings I'm seeing in the actual faders are exactly what you get from factory preset number 1, the stock default, as though it hadn't loaded anything. If I look at other preset buttons, they all show factory presets also. If I manually browse and open a user preset file myself in the program's GUI, it never complains, and it seems to open, and the opened settings you get from doing that still look remarkably just like factory preset #1. So, in effect, I can't save my mixer settings, which is a shame, because on Hammerfall based chips they can get awfully complicated to re-create. The other problem is more of a nitpick: The level meter for analog in #8, the last analog input on my Multiface II, shows nothing, even when there's signal. Other programs see signal from that input, just not hdspmixer. It's not a practical hindrance, but it's unnerving. Anyone else seeing any of this stuff? By the way, I've been seeing this for years. Before I ran Gentoo, I was on Debian. It's been true on both distros across several versions of the alsa-tools package, at least here on this system. -- + Brent A.

Specimen/Petri-foo settings

by Brent Busby

I looked around for documentation on this, even looked at the source code, so I thought I'd ask here... Does anyone happen to know what the "cut" and "cut by" settings in Specimen's and Petri-foo's "Voice" tab do? Also, is there any way to make one sample cut off another in Petri-foo, such as a hi-hat choke as offered by the Mute Groups in Hydrogen? -- + Brent A.

This whole thread is about loop points set in the WAV header (see topic), and whether it's supported in various programs.

I've just used the "Loop Start" and "Loop End" cue points position, since the loop cue's are very of often labelled like that. But it seems like the correct way to get the loop points are to parse the "smpl" chunk, as you say. Very good to know. :-)

Salamander drumkit, kick makes noises

by rosea.grammostola

Hi, The kick of the Salamander drumkit is making noises when it is trickered via midi. Key 35 in all.sfz. Kick2 seems to behave better noises: http://ubuntuone.com/3tkknbrsIxb6TDvABS9Grb Regards, \r

Fwd: Wav loop points

by Danni Coy

Yes you are basically splitting the sample up into attack,sustain and decay where the sustain can be looped for as long as needed but the decay is always played afterwards. This also works for musical passages where you have a passage that has a definite start phrase and end phrase with a repeating middle phrase that you may want to vary the number of repetitions based on how long the song ends up being.

Re: [LAU] Linux-audio-user Digest, Vol 70, Issue 13

Louigi Verona: > Hey fellas! > > I notice that no Linux samplers seem to support wav file loop points. > All That's not correct. The sampler in radium supports wav file loop points: https://github.com/kmatheussen/radium/blob/master/audio/Sampler_plugin_wav_… I'm surprised you haven't found anyone else though. It's extremely useful.
