如何修复此SyntaxError：意外的标识符？

on.pitch = event.value+GetParameter('Starting Note'+' 'event.channel)+GetParameter('Number'+' 'event.channel)*12;

错误是：

[JS Exception] SyntaxError: Unexpected identifier 'event'. Expected ')' to end a argument list. line:4

删除event之前的单引号：

on.pitch = event.value+GetParameter('Starting Note '+event.channel)+GetParameter('Number '+event.channel)*12;
