I bought the Midi din to USB converter and was very ,very happy with the service,and the converter, which works with all my gear flawlessly.I mainly got it to use with an Arq-96 but it works with everything I have ,including an Akai Mpk mini,which it also supplies buss power to.Delivery was extremely quick and I was kept informed about delivery time.This item was half the price of similar items elsewhere,and excellent quality so will definitely be buying from Hobbytronics again.If anyone has USB midi gear and needs to either send or receive midi through standard 5pin midi leads ,then this is super useful ,and opens up loads of gear to many more uses.
