My son is autistic and he will be 12 in April and he likes to play on devices that make strange sounds. Yesterday we were in a music shop and they had a Roland DJ synth with full envelope control and he was in his element. But thats very expensive and needs amp, speakers etc. What we want for him is something like that but in one unit for about 50 or £60 if possible. At the moment he has an old Yamaha prs with a broken key. Thats fine but he likes to make odd sounds more than making music (that might come later)
