This thing has been nothing but a massive headache. Maybe it is because I am new to this and I'm doing something wrong(didn't have the twiddler 3), but the twiddler 4 simply isn't a functional product on my end. At first, at it was the BT dropout issues while sitting at my computer. Tony helped guide me through that, which I'm thankful for. Unfortunately, there have been a number of other issues. I'm trying to use the tuner to create custom combo keys, for example, I want to press something like T1 and 1R and get a hotkey combo in Voicemod to register two keys, such as '* + A'. The biggest key combo I can get out of this is a modifier button, such as shift or alt, and a single key like 'A', to give me a hotkey combo of 'Shift + A' which isn't what I want. I've tried adding delays...everything. I updated the firmware at the suggestion of Tony, and that really only made things worse. Now, my computer no longer can recognize the bluetooth device. Tony has now stopped replying to my messages for help. I bought two of these, and along with shipping, it cost a significant sum. Maybe someone else has some advice how to move forward with this product and get it to work properly? Thank you, I really want to get this thing working.
