USB to Serial port solutions for MIDI

The one constant in the world is change, and as technology progresses it can be easy to feel left behind. Of course this never happens faster than with computers…

“I’ve been perfectly content over the years utilizing my serial port MIDI interfaces along with my Macs. My last configuration was an Opcode Studio 4 linked to a “beige” G3. The computer had serial input so everything was just dandy. Now I’ve gone and updated computers to a USB only G4. I thought I would simply need a USB to serial converter in-line between the computer and the interface but I read an article the other day that hinted that this may not be the case. So can you please give me the definitive word on whether this Studio 4 can continue to be a tool for me or has it just become a very expensive door stop?”

Nah, it’s too small to make a good door stop. But seriously folks, there is a solution. In general we’ve found that the USB to serial converter boxes work very poorly or not at all with MIDI. However, there are a couple of good solutions for you. You can get a PCI card that will give you one or more serial ports or you can buy a device that plugs into your internal modem slot. Your need for an internal modem or all three of your PCI slots may push you in one direction or the other. There are different versions of these devices for the G3, G4, G4 Sawtooth, and iMac so be sure to talk to your Sweetwater Sales Engineer for specifics.

The Studio 4 is a great MIDI interface, but you should also bear in mind that there are some advantages to the newer models. USB interfaces offer conveniences like hot swapping and ease of networking multiple units together, but they are also capable of much more data throughput and some manufacturers are starting to take advantage of this by offering enhancements such as MTS and other performance features. I’m not saying you need to dump the Studio 4, but depending upon your needs you may want to take a look at what’s out there. Again, this is where your Sweetwater Sales Engineer can help.

Finally, when it comes to computer technology it’s pretty difficult to come up with the “definitive” word on anything because stuff changes every day. What we say here is true today, but in a month all bets may be off. Welcome to the bleeding edge…

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
