I fail to get a tam-tam sound
I´m trying to make an instrument change in the cymbal part to get a tam-tam (sort of a large cymbal or, rather, a gong) in an ochestral score. I find, in the Orchestra / Percussion - unpitched menu, a Tam-tam option. However, when a note is inserted it doesn't sound like a tam-tam, i.e., a low-pitch sound, but as a higher-pitch sound. The infomation that pops up in the mixer indicates bank 128 program 48 for the cymbal and bank 128 program 0 for the tam-tam.
How can I select something that approximates better a real tam-tam?
