The Linux audio community can be pretty bad – there are some very entrenched views and woe betide you fall outside the group-think. I turned my back on a major part of the community at the beginning of the year, after about 9 years, after I saw a very ugly side to its nature.
I'm pragmatic. I don't care about things being FLOSS, I don't care about them being commercial, I don't care about them being non-Linux. The linuxDSP plugins are superb, I wish there were more of them.
I'm a recent convert to Pianoteq and am very grateful that they support Linux. That came about because I built a new PC at the end of last year and updated to the latest UbuntuStudio and try as I might, I couldn't get NI's B4II or Elektrik Piano to work under Wine, when they had worked fine on my old machine (never had to re-authorise after I first installed them on that old machine and it was five years old when I retired it). So I ditched B4 for VB3 which works perfectly under Wine and Elektrik Piano for Pianoteq. I've also now ditched all the Gigasampler pianos because they can't stand up to Pianoteq.
Shortly after I replaced them I managed to get the NI plugins working
But I prefer VB3 and Pianoteq.
The biggest worry I had was that I couldn't get M-Tron Pro to work. VSM was less of an issue as I now have that base covered to some degree by hardware. For the music I make I couldn't face a life without Mellotron so it was a relief when I got it to work. Taijiguy's samples, that I packaged in Giga for LinuxSampler, are great but there's not the diversity that M-Tron offers.
It's things like that that are lacking for me: there are certain sounds, such as accurate Hammond emulation, decent classic synth emulation (doesn't bother me now I'm entirely hardware on the synth front), Mellotron, that you just can't get under Linux. For some that means they don't have access to those sounds, but as I say, I'm pragmatic and have no qualms about using non-FLOSS, commercial, Windows software tools to get the job done. It would be very nice to have native options – things suddenly not working with Wine is always a major worry – but it doesn't bother me.
The other area I feel it's lacking is sampling. Gigastudio is now very old so there are no new libraries for it and very few older ones, Linuxsampler doesn't support all the features (convolution was always a bummer) and development on it seems glacially slow. SFZ seems a bit more promising; I've just spent ages remapping drum samples and it's far easier to work with than Gigedit and Giga files. Oh yeah, that's another bugbear: drum programming.
Hydrogen's development is glacially slow as well. Plus it seems to have a crisis of identity and is woefully lacking in certain areas (as development seems to be heading off on a tangent). So in the last week I've decided to ditch Hydrogen completely, switching to Carla or LS and SFZ. It's going to be a steep learning curve to programme in Ardour, but I'm sure it'll be worth it and will be better in the end. Ardour's midi still seems a bit unstable, but at least visible progress is being made and it's getting there.
Which all sounds like a major bitch, but I'm actually a happy Linux audio user (in the general sense) and have been since 2005.
