For a good Microphone you might look into the Shure Beta line, ie., 54,58,87,. The Beta 54 is a head worn mic. A good Mic for Instruments is the Shure KSM109. Another great Mic is the Neumann KMS 105 handheld. It is arguably the best handheld on the market for vocals although you will pay dearly for it, ie., around $600 USD.
For good notation software Finale is the best selling notation software and it is considered top of the line. A comparison would be: "the Photoshop of Music Notation software", if your familiar with Photoshop. You probably are if you have a Mac. To purchase Finale in Finland you can find it in Rajamaki at Hellas Piano or at their online store at:
www.hellaspiano.com I would shop around online to try and get the best price though. In the USA there are special prices for College Students and I think it applies to Students worldwide.
PS: Maybe your Folks could help you out financially (Birthday, Christmas, gift) type thing; for some of your new gear although you may have all the finances you need already.
Best regards Micco,
Mike
