(Ardour) How to get rid of delay when recording ?

by jonetsu＠teksavvy.com

Hello, When recording acoustic guitar wearing headphones, the delay between the note being played and the headphone output is so noticeable that for fingerpicking with only but a soft synth pad as background, it is difficult to play a good track. It is way too distracting. The workaround is to put a click, a high hat for instance and be oblivious of anything else and try for the best. But it is certainly not free playing as if playing along when the same is coming out the speakers. In Ardour 4.6.0 changing the monitoring from Ardour to hardware does not improve anything. Any advice, hints, suggestions will be much appreciated. Here is the setup. 1010LT card with playback outputs 3 and 4 send to a Behringer HA400 headphone amp. Just about no plugins in Ardour, No xruns seen in quite some time (eg. i5 3.40GHz CPU is very likely running under no stress) 16G RAM. It would be so nice to have no delay at all! Cheers.

android 5.1 tablet klipad smart i745

by fred

Hi list, have had this android 5.1 tablet klipad smart i745 as a gift, and it will be fun to use it to do the fader automation in Ardour. Is there somebody on the list, that could say that it's possible to do, or if am losing my time to try this? At this point, am always searching a way to communicate between the tablet and the pc, and am not sure at all if it's via USB or thru the router that it have to be done.. Thanks! -- Fred

Re: [LAU] Ardour: use case for monitor plug-in ?

That is not correct (DRC only for Windows). If you read just a little past the section 4 with the theory of operation, section 5 begins with this: "DRC can be compiled either under Win32 or Linux, but because of its simplicity it will probably work under most operating systems with a decent C++ compiler with support for the standard template library (STL)." -- Chris Caudle

Alternative to jack-play

by Michael Jarosch

Hi, there! I'm searching for an alternative to jack-play. I don't like using an environment variable. The main use is to send different one-shot-samples across different outputs of my HDSP9652 in a bash-script (or similar). What are my options? Greets! Mitsch

Music recorded with Linux : c2016-03

by jonetsu＠teksavvy.com

Hello, This is a short improv on a simple riff. Two acoustic guitars, one acoustic bass guitar, a bit of synth here and there. A bit more than a minute and a half. What's new here is the use of two mics for the instruments. I have a M-Audio Pulsar (not Pulsar 2) that I forgot about since I got the AT-2020 a year ago. So I uncovered it, plugged it, aimed both and pressed record. The strumming went along. I kept it, then I added the lead and bass, and some colours. Then fiddled a bit with the volumes, EQ, reverb (using the free U-he Protoverb), wave volume editing in Ardour. Enjoy: https://soundcloud.com/nominal6/c2016-03 Cheers.

GeneralMusic RealPiano Expander, FREE

by Stephen Doonan

I have a GeneralMusic RealPiano Expander tone generator, a one-unit high rack-mount half-width hardware sound source, to give away free to someone who may be interested. This sound module or tone generator responds to MIDI signals and produces a variety of sounds (pianos, electric pianos, vibes, etc.). It was very well-regarded in its day (just 12-15 years ago), and GeneralMusic was famous for modeling sympathetic string resonance into their piano samples/sounds, before Roland later "invented" modeled string resonance for their piano sound engines in their digital pianos (such as the current RD-800) and rack-mounted tone generators (such as the Integra-7). This GeneralMusic tone generator still works great, EXCEPT that the front LCD display seems to be nearly worn out and does not give a very good indication of changes made when front-panel buttons are pushed. I'm not enough of an electronic tinkerer to fix or replace the LCD screen, so this tone module might better be given to someone who is more proficient at taking electronic devices apart and working a little on them. It's free to whomever might like it, although if the shipping expenses are high I might ask the recipient to help pay for the shipping. It's a small unit though and shouldn't cost too much to ship within the United States, and perhaps not too much to ship to Europe or elsewhere with help from the recipient. If you are interested in this very nice, somewhat older MIDI tone generator / sound-module, let me know at my email address, stephen.doonan(a)gmail.com I may not choose the first person to express an interest in the device; instead, I will consider several factors before making a decision as to whom to give it to. I love the sounds it produces, but as I mentioned it needs a little work (unless someone wants to use it "blind," without having much feedback from the LCD screen (the manual will be included)) and have plenty of other sound sources to work with now. Best wishes, Steve -- My Music: https://soundcloud.com/stephendoonan/

Yamaha MU90R Tone Generator, FREE

by Stephen Doonan

Free giveaway -- Yamaha MU90R tone generator (rackmount) Preferred recipient -- Linux audio developer or group Hello all-- I have a Yamaha MU90R one-unit-high rackmount tone generator (sound module) for giveaway (I may ask the recipient to pay the shipping cost, however). This unit is fully functional (unlike the GEM RealPiano Expander I offer in another discussion thread which has a defective LCD display) and in great shape. Thanks to suggestions in the RealPiano Expander thread, I would like to donate this rackmount unit to a person or group involved in some way with Linux audio development or promotion, if they think it might be useful. A search at Google or DuckDuckGo.com (ddg.gg) for "Yamaha MU90R" will yield many results for images, YouTube videos, manuals, information, etc. Best wishes, Steve --- My SoundCloud music: https://m.soundcloud.com/stephendoonan
