Actually....I wish I could play just about any/every musical instrument out there
That said....there's probably few instruments that I could do a quick study on just enough to be able to use them for some basic "ear candy" in a recording if I really needed them.
I feel a similar way. I can play various drums, congas and bongos but there was a time when I wished I'd learned the actual drum kit.
The reason I didn't and don't is because there's always been drummers around that I've been friends with and they would play on my stuff so there was no real urgency to learn.
I don't think I play any instrument "well", but again, I don't really need to. I can find my way around the mandolin and various keyboards and multitracking has always enabled me to be a naughty boy in
the studio and use some jiggery pokery to achieve certain desired results.
I'm fortunate in that I know a number of instrumentalists and vocalists but I'd love to have access to a sitarist, a tabla player, a trumpeter and a viola or violinist.
put me in front of a contrabass
The one instrument that I would really like to be able to play properly is the upright bass. I can get some decent sounds out of it
I used to have a double bass then I sold it 10 years ago when the VSTi bug bit. The bug actually bit because of a sensational double bass sample I heard that came on a CD with Computer music or Sound on sound. I assumed a great double bass VSTi would be easy to find.......how wrong I was. I never found one that approached the quality of the one I heard back in 2004. The bowed sounds were OK but it was the pizzicato sounds I really wanted. As dismissive as this sounds, every one I heard was......well, unsatisfactory. Also, it was weird playing them off a keyboard, which never bothered me with other instruments that you bow or blow. So, in 2012 I just went out and bought a cheap 3/4 size one. I figured that even a shitty cheap one that I could play with my cackhandedness was better than any sample/VSTi {The same thing had happened with drums, I had an electric kit for a couple of years but for
me, nothing beats
the acoustic kit so I bought one again, which 8 years on I still have and use}. I worked out where the semitones are, painted fretlines and set up the bridge myself. I don't care if it looks ugly.
It's beautiful to my ears.
