FOR IMMEDIATE RELEASE

MAKEMUSIC REPORTS FOURTH QUARTER AND FISCAL YEAR 2012 RESULTS

Minneapolis – March 13, 2013– MakeMusic, Inc. (NASDAQ: MMUS), a world leader in music technology, announced financial results for the period ended December 31, 2012. As previously announced and further explained below, MakeMusic has entered into a definitive agreement with LaunchEquity Partners, LLC pursuant to which MakeMusic expects to be acquired in an all-cash transaction.

Chairman of the Board Robert Morrison commented, “Our SmartMusic^® business performed well during the fourth quarter and we continued our work to launch new and enhanced versions of Finale^® and SmartMusic in mid-2013. We are pleased with the progress we are making towards these goals, as well as with our other product development, sales and marketing initiatives, including our upcoming release of an iPad^® version of SmartMusic. We remain focused on developing and offering fresh and innovative solutions that advance the ways in which music is composed, taught, learned and performed.”

COO and CFO Karen VanDerBosch added, “SmartMusic subscriptions rose to 209,418 as of December 31, 2012, a 17% year-over-year increase and SmartMusic revenue increased by 15% in 2012. This growth was offset by a decline in notation revenue, reflecting year-over-year changes in the timing of a new release of Finale. Our push to modernize our notation software platform is on schedule and we look forward to unveiling the new product mid-year. In addition, we completed our rebranding initiatives to achieve a more consistent look and feel for our products. Just last week we launched a new version of MakeMusic’s website that has our new branding and enhanced e-commerce capabilities.”

Financial Results for the Quarter Ended December 31, 2012 Compared to the Quarter Ended December 31, 2011

Financial Results for the Year Ended December 31, 2012 Compared to the Year Ended December 31, 2011

Cash and cash equivalents were $5.7 million compared to $9.3 million as of December 31, 2011. The decrease is attributable primarily to our technology and sales and marketing investments, as well as our strategic alternatives review process.

In light of MakeMusic’s pending acquisition by LaunchEquity, MakeMusic will not conduct a conference call to review the company’s financial results.

LaunchEquity to Acquire MakeMusic

On March 13, 2013, LaunchEquity Partners, LLC and MakeMusic, Inc. announced a definitive merger agreement, pursuant to which LaunchEquity would acquire MakeMusic, subject to satisfaction of customary closing conditions, in an all-cash transaction. The transaction is structured as a tender offer followed by a back-end merger. At the effective time of the merger, each share of common stock that has not been tendered and accepted at the offer price of $4.85 per share in the tender offer (other than shares owned by LaunchEquity or its affiliates or shares subject to perfected appraisal rights under applicable law) will be converted into the right to receive the offer price of $4.85 per share. MakeMusic anticipates that tender offer materials will be provided to shareholders around the end of March 2013.
